Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

Before introducing the information transmission method, device, medium and electronic equipment based on the intelligent network provided by the disclosure, an application scenario involved in each embodiment of the disclosure is first described, where the application scenario may include a terminal device, an intelligent network cloud control platform and an authentication node. The terminal equipment, the intelligent network cloud control platform and the authentication node can communicate through any protocol of 5G (English: the 5th Generation mobile communication technology, chinese: fifth generation mobile communication technology) and 4G (English: the 4th Generation mobile communication technology, chinese: fourth generation mobile communication technology), WLAN (English: wireless Local Area Networks, chinese: wireless local area network), telematics (Chinese: automobile information service), V2X (English: vehicle to Everything, chinese: internet of vehicles). For example, the terminal device, the intelligent network cloud control platform and the authentication node can perform V2X communication based on LTE (english: long Term Evolution, chinese: long term evolution) -Uu mode in a 5G scenario. The terminal device may be an intelligent network terminal device disposed On a vehicle, for example, an OBU (On board Unit, chinese: vehicle Unit), a camera, a millimeter wave radar, a lidar, and various environmental sensing devices, where the vehicle may be an automobile, and the automobile is not limited to a conventional automobile, a pure electric automobile, or a hybrid automobile, but may be other types of automobiles or non-automobiles. The terminal device can also be other intelligent network terminal devices, such as RSU (Road Side Unit, english), traffic signal lamps, marks, graticules, guardrails and other intelligent traffic control facilities. The authentication nodes can be one or more, and the intelligent networking cloud control platform and the authentication nodes are both deployed on the server. The intelligent network cloud control platform and the authentication node can be deployed on the same server or on different servers, and the disclosure is not limited in particular. The server may include, but is not limited to: entity servers, server clusters, cloud servers, and the like.

Fig. 1 is a flowchart illustrating an intelligent networking-based information transmission method according to an exemplary embodiment. As shown in fig. 1, the method may include the following steps applied to the terminal device:

and step 101, generating internet of vehicles information according to a first authentication token contained in the first authentication information sent by the authentication node, wherein the first authentication token is used for identifying the terminal equipment.

For example, in order to improve the security and the credibility of the internet of vehicles information, a special authentication node may be provided to allocate an authentication token and a key to the terminal device and the intelligent network cloud control platform, so as to authenticate the validity of the terminal device that needs to be accessed to the intelligent network cloud control platform by using the allocated authentication token, and encrypt the internet of vehicles information transmitted between the terminal device and the intelligent network cloud control platform by using the allocated key. Specifically, before the terminal device and the intelligent network cloud control platform perform information communication, an authentication request can be sent to the authentication node by the terminal device, wherein the authentication request includes terminal identification information corresponding to the terminal device. For example, when the terminal device is an OBU, the terminal identification information may include owner information, vehicle number information, a registration ID (English: identity document) of the terminal device, and the like.

After receiving the authentication request, the authentication node may send first authentication information including a first authentication token and a first key to the terminal device, and send second authentication information including a second authentication token and a second key to the intelligent network cloud control platform. After receiving the first authentication information, the terminal device can update the acquired internet of vehicles information according to the first authentication token to obtain updated internet of vehicles information. The internet of vehicles information may include: at least one of BSM (English: basic Safety Message, chinese: basic safety message), RSI (English: road Side Information, chinese: road side information), RSM (English: road Safety Message, chinese: road side safety message), SPAT (English: signal phase timing message, chinese: traffic light phase and timing message) and MAP (Chinese: MAP message). The method for updating the internet of vehicles information according to the first authentication token may be: the first authentication token is added to the internet of vehicles information. For example, when the internet of vehicles information is a BSM, the terminal device may extend a communication protocol of the BSM, and newly add an optional field token (an optional field may be represented by, for example, 16-ary characters with a fixed length of 8 bits) based on the original national standard BSM message set, so as to record the first authentication token, so as to add the first authentication token to the BSM message set. The structure of the updated BSM message set may be as shown in table 1:

TABLE 1

And 102, encrypting the Internet of vehicles information according to a first key included in the first authentication information to obtain target Internet of vehicles information.

In this step, the terminal device may first encode the internet of vehicles information by using a preset encoding and decoding manner, so as to obtain encoded internet of vehicles information. Since the asn.1 (english: abstract Syntax Notation One, chinese: abstract syntax notation) codec is associated with multiple standardized coding rules, it is capable of supporting fast and reliable transmission of scalable information. Therefore, the preset encoding and decoding mode can adopt ASN.1 encoding and decoding. Then, the terminal equipment can encrypt the encoded internet of vehicles information according to the first secret key to obtain target internet of vehicles information, so that the security of the internet of vehicles information is ensured. For example, the terminal device may encrypt the internet of vehicles information by using a 16-bit MD5 Message-Digest Algorithm (MD 5 for short) and using a first key to obtain the target internet of vehicles information by AES (english Advanced Encryption Standard, chinese advanced encryption standard).

Step 103, the target internet of vehicles information is sent to the intelligent internet of things cloud control platform, so that the intelligent internet of vehicles cloud control platform decrypts the target internet of vehicles information according to a second secret key included in the second authentication information sent by the authentication node, under the condition that the target internet of vehicles information is successfully decrypted, whether a first authentication token included in the internet of vehicles information is matched with a second authentication token included in the second authentication information is determined, and under the condition that the first authentication token is matched with the second authentication token, the internet of vehicles information is processed.

For example, after obtaining the target internet of vehicles information, the terminal device may send the target internet of vehicles information to the intelligent internet cloud control platform. And decrypting the target internet of vehicles information by the intelligent network cloud control platform according to the second secret key, and if the target internet of vehicles information is successfully decrypted, obtaining the internet of vehicles information in the target internet of vehicles information. When the information is to be encrypted, the first key is used for encrypting the information, the second key is used for decrypting the corresponding information, and the first key and the second key may be the same or different, for example, the first key is a public key, and the second key is a corresponding private key. And then the intelligent networking cloud control platform decodes the internet of vehicles information (for example, ASN.1 encoding and decoding can be adopted to decode the internet of vehicles information) so as to obtain the decoded internet of vehicles information. And then the intelligent network cloud control platform can acquire the first authentication token and the terminal identification information included in the decoded internet of vehicles information, and determine whether the first authentication token is matched with the second authentication token received by the intelligent network cloud control platform according to the first authentication token and the terminal identification information. If the first authentication token is matched with the second authentication token, the intelligent network cloud control platform can determine that the terminal equipment is legal equipment. Under the condition that the terminal equipment is determined to be legal equipment, the intelligent networking cloud control platform can process (e.g. store, calculate and analyze) the internet of vehicles information, so that the intelligent networking cloud control platform can push the service to the terminal equipment based on the internet of vehicles information.

In summary, the present disclosure firstly generates internet of vehicles information according to a first authentication token included in first authentication information sent by an authentication node, then encrypts the internet of vehicles information according to a first key included in the first authentication information to obtain target internet of vehicles information, sends the target internet of vehicles information to an intelligent internet of vehicles cloud control platform, so that the intelligent internet of vehicles cloud control platform decrypts the target internet of vehicles information according to a second key included in second authentication information sent by the authentication node, and determines whether the first authentication token included in the internet of vehicles information is matched with a second authentication token included in the second authentication information when the target internet of vehicles information is successfully decrypted, and processes the internet of vehicles information when the first authentication token is matched with the second authentication token. According to the method and the device, the validity of the terminal equipment accessing the intelligent network cloud control platform is authenticated through the first authentication token and the second authentication token, the credibility and the safety of the internet of vehicles information are improved, the internet of vehicles information is encrypted and decrypted through the first secret key and the second secret key, and the safety of the internet of vehicles information transmission process is improved.

Fig. 2 is a flow chart illustrating another intelligent networking-based information transfer method according to an exemplary embodiment. As shown in fig. 2, the method further comprises the steps of:

step 104, sending an authentication request to the authentication node so that the authentication node generates a first key, generates a first authentication token according to the authentication request, and encrypts the first authentication token and the first key into first authentication information according to a first rule.

Step 105, receiving the first authentication information sent by the authentication node, and decrypting the first authentication information according to the first rule to obtain a first authentication token and a first key.

For example, the terminal device may send an authentication request including terminal identification information to the authentication node. After receiving the authentication request, the authentication node can determine whether target terminal identification information matched with the terminal identification information exists from a plurality of pieces of identification information included in a preset identification information base. For example, in the case where the terminal identification information includes the vehicle owner information, the vehicle number information, and the registration ID of the terminal device, the authentication node may determine whether there is identification information in which the vehicle owner information, the vehicle number information, and the registration ID of the terminal device are identical to the terminal identification information, respectively, among the plurality of identification information included in the identification information base. If the target identification information exists, the authentication node can take the identification information as the target identification information, and if the target identification information does not exist, the authentication node determines that the target identification information does not exist. If the target terminal identification information exists, the terminal equipment is legal equipment, the authentication node can generate a first key which is agreed with the terminal equipment in advance, and a first authentication token is generated by combining the terminal identification information by using a preset algorithm. Wherein the first authentication token is a unique random string (the random string may be a 64-bit, 128-bit or 256-bit string) for identifying the terminal device, and the preset algorithm may be a hash algorithm. The specific implementation manner of generating the first authentication token may refer to the manner described in the related art, and will not be described in detail herein.

Then, the authentication node may encrypt the first authentication token and the first key according to a first preset rule agreed with the terminal device to form first authentication information according to the first rule, and send the first authentication information to the terminal device. After receiving the first authentication information sent by the authentication node, the terminal device may decrypt the first authentication information according to a first rule to obtain a first authentication token and a first key. The first preset rule may be set according to a registration ID of the terminal device, a preset key change period and an offset, for example, and the change rule of the target key used for encrypting the first authentication token and the first key, that is, the authentication node and the terminal device node may determine the currently used target key through the first preset rule.

Fig. 3 is a flow chart illustrating yet another intelligent networking-based information transfer method, according to an exemplary embodiment. As shown in fig. 3, the method further comprises the steps of:

and step 106, receiving key updating information sent by the authentication node, wherein the key updating information is obtained by encrypting the third key by the authentication node according to the second rule.

And step 107, decrypting the key updating information according to the second rule to obtain a third key, and updating the first key to the third key.

In one scenario, in order to further improve the security of the internet of vehicles information, the first key and the first rule may be updated periodically, so as to avoid leakage of the first key and the first rule. For example, the authentication node may generate a new third key agreed in advance with the terminal device, then encrypt the third key according to the second rule to obtain key update information, and send the key update information to the terminal device. After receiving the key updating information sent by the authentication node, the terminal device may decrypt the key updating information according to the second rule to obtain a third key, and update the first key in the terminal device to the third key. The second preset rule may be a rule pre-agreed with the terminal device, and the target key change rule obtained after the registration ID, the preset key change period and the offset of the terminal device in the first preset rule are adjusted, that is, the authentication node and the terminal device node may determine the target key used after updating through the second preset rule. The second preset rule may be the same as or different from the first preset rule, which is not specifically limited in this disclosure.

Fig. 4 is a flowchart illustrating a method of intelligent networking based information transfer, according to an exemplary embodiment. As shown in fig. 4, the method may include the following steps:

step 201, receiving target internet of vehicles information sent by target terminal equipment. The target internet of vehicles information is obtained by encrypting the internet of vehicles information by the target terminal equipment according to a first key included in first authentication information sent by the authentication node, the internet of vehicles information is generated by the target terminal equipment according to a first authentication token included in the first authentication information, and the first authentication token is used for identifying the target terminal equipment.

And step 202, decrypting the target internet of vehicles information according to a second key included in the second authentication information sent by the authentication node.

And 203, if the target internet of vehicles information is successfully decrypted, acquiring the internet of vehicles information.

For example, after receiving the first authentication token and the first key sent by the authentication node, the target terminal device may update the acquired internet of vehicles information according to the first authentication token, and encode the updated internet of vehicles information by adopting a preset encoding and decoding manner, so as to acquire encoded internet of vehicles information. And the target terminal equipment can encrypt the encoded internet of vehicles information according to the first key to acquire target internet of vehicles information and send the target internet of vehicles information to the intelligent internet cloud control platform. And decrypting the target Internet of vehicles information by the intelligent Internet cloud control platform according to the second key. If the intelligent network cloud control platform successfully decrypts the target internet of vehicles information, the internet of vehicles information in the target internet of vehicles information can be obtained, and the internet of vehicles information is further decoded by using a preset encoding and decoding mode, so that the decoded internet of vehicles information is obtained. If the intelligent network cloud control platform does not successfully decrypt the target internet of vehicles information, the intelligent network cloud control platform indicates that the target terminal equipment is not legal equipment, and the intelligent network cloud control platform can directly discard the target internet of vehicles information.

Step 204, determining whether the first authentication token included in the internet of vehicles information matches the second authentication token included in the second authentication information.

And step 205, if the first authentication token is matched with the second authentication token, processing the internet of vehicles information.

For example, the intelligent network cloud control platform may store second authentication tokens corresponding to a plurality of terminal devices and second terminal identification information corresponding to each second authentication token. After the internet of vehicles information is acquired, the intelligent internet of things cloud control platform can acquire a first authentication token and first terminal identification information corresponding to the first authentication token, which are included in the decoded internet of vehicles information, and determine whether the first authentication token is matched with the second authentication token according to the first authentication token and the first terminal identification information. The manner of determining whether the first authentication token matches the second authentication token may be: first, whether second terminal identification information identical to first terminal identification information exists or not is determined, and if the second terminal identification information identical to the first terminal identification information exists, whether a second authentication token corresponding to the second terminal identification information is identical to the first authentication token or not is determined. And if the second authentication token corresponding to the second terminal identification information is the same as the first authentication token, determining that the first authentication token is matched with the second authentication token, otherwise, determining that the first authentication token is not matched with the second authentication token. If the first authentication token is matched with the second authentication token, the intelligent network cloud control platform can determine that the terminal equipment is legal equipment. And under the condition that the terminal equipment is legal equipment, the intelligent network cloud control platform can process the Internet of vehicles information so that the intelligent network cloud control platform can push the service to the terminal equipment based on the Internet of vehicles information. If the first authentication token is not matched with the second authentication token, the target terminal device is not legal device, and the intelligent networking cloud control platform can directly discard the Internet of vehicles information.

Fig. 5 is a flow chart illustrating another intelligent networking-based information transfer method according to an exemplary embodiment. As shown in fig. 5, the method further comprises the steps of:

and step 206, receiving second authentication information sent by the authentication node. The second authentication information comprises a second key generated by the authentication node and a second authentication token generated by the authentication node according to an authentication request sent by the terminal equipment, wherein the terminal equipment is target terminal equipment or other terminal equipment except the target terminal equipment.

For example, after receiving an authentication request sent by the terminal device, the authentication node may generate a second key that is agreed in advance with the intelligent network cloud control platform, then combine the terminal identification information with a preset algorithm to generate a second authentication token, and send the second key, the second authentication token and the terminal identification information corresponding to the terminal device to the intelligent network cloud control platform as second authentication information. And the intelligent network cloud control platform receives the second authentication information sent by the authentication node and stores the second secret key, the second authentication token and the terminal identification information. Wherein the second authentication token is a unique random string for identifying the terminal device.

If the second authentication information is transmitted by the authentication node after receiving the authentication request transmitted by the target terminal device, the first authentication token and the second authentication token are the same. If the second authentication information is transmitted by the authentication node after receiving the authentication request transmitted by the terminal device other than the target terminal device, the first authentication token and the second authentication token are different.

Fig. 6 is a flowchart illustrating yet another intelligent networking-based information transfer method, according to an exemplary embodiment. As shown in fig. 6, the method further comprises the steps of:

step 207, receiving the fourth key sent by the authentication node, and updating the second key to the fourth key.

In one scenario, in order to further improve the security of the internet of vehicles information, the second key may be updated periodically, so as to avoid leakage of the second key. For example, the authentication node may send the fourth key that is pre-agreed with the intelligent network cloud control platform to the intelligent network cloud control platform, so that the intelligent network cloud control platform updates the second key to the fourth key.

In summary, the present disclosure first receives target internet of vehicles information sent by a target terminal device, where the target internet of vehicles information is obtained by encrypting the internet of vehicles information by the target terminal device according to a first key included in first authentication information sent by an authentication node, the internet of vehicles information is generated by the target terminal device according to a first authentication token included in the first authentication information, the first authentication token is used to identify the target terminal device, then decrypts the target internet of vehicles information according to a second key included in second authentication information sent by the authentication node, if decryption of the target internet of vehicles information is successful, obtains the internet of vehicles information, and then determines whether the first authentication token included in the internet of vehicles information is matched with a second authentication token included in the second authentication information, and if the first authentication token is matched with the second authentication token, processes the internet of vehicles information. According to the method and the device, the validity of the terminal equipment accessing the intelligent network cloud control platform is authenticated through the first authentication token and the second authentication token, the credibility and the safety of the internet of vehicles information are improved, the internet of vehicles information is encrypted and decrypted through the first secret key and the second secret key, and the safety of the internet of vehicles information transmission process is improved.

Fig. 7 is a flowchart illustrating a method of intelligent networking based information transfer, according to an exemplary embodiment. Applied to an authentication node, as shown in fig. 7, the method may comprise the steps of:

step 301, receiving an authentication request sent by a terminal device.

Step 302, generating a first key and a second key, and generating a first authentication token and a second authentication token according to the authentication request, wherein the first authentication token is used for identifying the terminal equipment, and the second authentication token is used for identifying the terminal equipment.

For example, after receiving an authentication request sent by a terminal device, the authentication node may generate a first key and a second key that are pre-agreed with the terminal device, and generate a first authentication token and a second authentication token by combining terminal identification information with a preset algorithm.

In this scenario, after receiving an authentication request sent by a terminal device, the authentication node sends a first authentication token to the terminal device, which is the same as a second authentication token sent to the intelligent network cloud control platform, that is, both the first authentication token and the second authentication token are used to identify the terminal device. Accordingly, the first key and the second key may be the same or different. For example, when AES is used to encrypt the internet of vehicles information, the first key and the second key are the same, and at this time, the first key corresponding to each terminal device is the same for a plurality of different terminal devices. When the RSA is adopted to encrypt the Internet of vehicles information, the first secret key and the second secret key are different, the first secret key can be a public key, the second secret key can be a private key, and at the moment, for a plurality of different terminal devices, the first secret key corresponding to each terminal device is different.

Step 303, encrypting the first authentication token and the first key into first authentication information according to a first rule, and transmitting the first authentication information to the terminal device.

And step 304, the second secret key and the second authentication token are sent to the intelligent networking cloud control platform.

For example, the authentication node may encrypt the first authentication token and the first key to the first authentication information according to a first preset rule agreed with the terminal device, and send the first authentication information to the terminal device. After receiving the first authentication information sent by the authentication node, the terminal device may decrypt the first authentication information according to a first rule to obtain a first authentication token and a first key. The first preset rule may be, for example, a change rule of a target key used for encrypting the first authentication token and the first key, which is set according to a registration ID of the terminal device, a preset key change period, and an offset. The authentication node may then send the second key and the second authentication token to the intelligent networked cloud control platform.

It should be noted that, the authentication node may directly send the second key and the second authentication token to the intelligent network cloud control platform, or may encrypt the second key and the second authentication token according to a predetermined rule and then send the encrypted second key and the encrypted second authentication token to the intelligent network cloud control platform, which is not specifically limited in the disclosure.

Fig. 8 is a flowchart illustrating another intelligent networking-based information transfer method, according to an exemplary embodiment. As shown in fig. 8, the method further comprises the steps of:

in step 305, a third key and a fourth key are generated.

In one scenario, in order to further improve the security of the internet of vehicles information, the first key, the second key, the first rule and the second rule may be updated periodically, so as to avoid leakage of the first key, the second key, the first rule and the second rule. For example, the authentication node may generate a new third key according to a rule pre-agreed with the terminal device to update the first key in the terminal device, and may generate a new fourth key according to a rule pre-agreed with the intelligent network cloud control platform to update the second key in the intelligent network cloud control platform.

Step 306, encrypting the third key according to the second rule to obtain the key update information.

Step 307, the key update information is sent to the terminal device, so that the terminal device decrypts the key update information according to the second rule to obtain the third key, and updates the first key to the third key.

And step 308, the fourth key is sent to the intelligent network cloud control platform, so that the intelligent network cloud control platform updates the second key to the fourth key.

For example, after acquiring the third key and the fourth key, the authentication node may encrypt the third key according to the second rule to obtain key update information, and send the key update information to the terminal device. After receiving the key updating information sent by the authentication node, the terminal device may decrypt the key updating information according to the second rule to obtain a third key, and update the first key to the third key. The second preset rule may be a change rule of the target key, which is pre-agreed with the terminal device, and is obtained after the registration ID, the preset key change period and the offset of the terminal device in the first preset rule are adjusted. And then, the authentication node can send the fourth key to the intelligent network cloud control platform, and the intelligent network cloud control platform updates the second key to the fourth key.

In summary, the disclosure first receives an authentication request sent by a terminal device, then generates a first key and a second key, and generates a first authentication token according to the authentication request, where the first authentication token is used to identify the terminal device, the second authentication token is used to identify the terminal device, encrypts the first authentication token and the first key according to a first rule to form first authentication information, sends the first authentication information to the terminal device, and finally sends the second key and the first authentication token to the intelligent network cloud control platform. According to the method and the device, the validity of the terminal equipment accessing the intelligent network cloud control platform is authenticated through the first authentication token and the second authentication token, the credibility and the safety of the internet of vehicles information are improved, the internet of vehicles information is encrypted and decrypted through the first secret key and the second secret key, and the safety of the internet of vehicles information transmission process is improved.
