Description
Technical Field

Background
Developers use the USB tool to issue commands to the device that can query the device for information, control the state of the device, or download new firmware into the device. For example, in the actual production process, a USB communication function is added to the BOOT ROM of the chip, so that the chip can communicate with the BOOT ROM of the chip through a USB port to complete the firmware burning operation. In order to improve the security of USB communication, SoC manufacturers generally design a proprietary USB communication protocol to complete the above-mentioned development and debugging operations, and provide a complementary USB tool. However, an attacker can perform packet capture analysis through the USB analyzer, crack the private USB communication protocol, and provide the USB communication protocol to any third party, thereby developing a corresponding USB cracking tool to control the device to accomplish various illegal purposes, such as reading sensitive information stored in the device and downloading malicious codes into the device, which threatens the device and information stored in the device, and greatly destroys the security of the device.
At present, in order to prevent a malicious third party from using a self-developed USB tool to steal information stored in a device and even download a tampered firmware into the device to completely modify the behavior of the device, on one hand, the method in the industry generally performs a corresponding check on a command before the command such as data read/write and program operation is executed, so as to limit the effect of the command. For example, the range in which data can be actually read and written is limited for data read and write commands; and aiming at the program operation command, performing security verification on the program before the program is operated. Obviously, although the method of performing targeted check before command execution can achieve a certain protection effect, the method has many types of commands such as data read/write and program operation, and is difficult to perform thorough check on the commands. On the other hand, the industry generally limits the USB tools, and eliminates the USB tools developed by malicious third parties by verifying the validity of the USB tools. However, the conventional USB tool restriction method needs to introduce an additional verification chip, which increases the hardware cost of the device.

Developers use the USB tool to issue commands to the device that can query the device for information, control the state of the device, or download new firmware into the device. For example, in the actual production process, a USB communication function is added to the BOOT ROM of the chip, so that the chip can communicate with the BOOT ROM through the USB port to complete the firmware burning operation. In order to improve the security of USB communication, SoC manufacturers generally design a proprietary USB communication protocol to complete the above-mentioned development and debugging operations, and provide a complementary USB tool.

On the other hand, the industry generally limits the USB tools, and eliminates the USB tools developed by malicious third parties by verifying the validity of the USB tools. However, the conventional USB tool restriction method needs to introduce an additional verification chip, which increases the hardware cost of the device.
Therefore, the invention provides a USB communication object verification method and a system, which are different from the traditional USB communication object verification method and have the problems of poor flexibility and safety or need to introduce additional hardware; by directly verifying the communication object, the instruction content issued by the communication object does not need to be subjected to targeted limitation, so that the flexibility is improved; the communication object is verified in a mode of generating the random number, encrypting the random number through the communication object and decrypting the random number ciphertext through the equipment end, extra hardware is not needed to be introduced, the cost is reduced, the random numbers generated in each verification process are inconsistent, and the safety of the equipment is further improved.
A USB communication object authentication method and system according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings, and first, a USB communication object authentication method according to an embodiment of the present invention will be described with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention provides a USB communication object verification method, where the USB communication object verification method in the embodiment of the present invention may be applied to a terminal, a server, or software running in the terminal or the server. The terminal may be, but is not limited to, a tablet computer, a notebook computer, a desktop computer, and the like. The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a network service, cloud communication, middleware service, a domain name service, a security service, a Content Delivery Network (CDN), a big data and artificial intelligence platform, and the like. The USB communication object verification method in the embodiment of the invention mainly comprises the following steps:
s101, generating a random number and a first instruction according to a first request;
wherein the first request is a connection request sent by the communication object.
Specifically, the communication object sends a connection request to the device, and the device generates authentication information including a random number and a first instruction for authenticating the communication object after receiving the connection request. It can be understood that the random number has the characteristic of randomness, the random number generated in the process of authenticating the communication object every time has randomness, and the communication object is difficult to authenticate by copying and retransmitting the generated communication data, so that the reliability of the authentication of the communication object is improved, and the safety of the device is improved.
S102, after the communication object receives the random number and the first instruction, encrypting the random number according to the first instruction and a first key to generate first data;
in one embodiment of the present invention, the first key is a private key of an RSA encryption algorithm in a legitimate communication object (a communication object associated with a device). It can be understood that if the communication object is a USB tool developed by a third party, the private key cannot be held, and the encrypted ciphertext generated by encrypting the random number is different.
Specifically, after receiving the random number and the first instruction, the communication object encrypts the random number according to the first instruction and a first key to generate an encrypted ciphertext, that is, the first data.
In the embodiment of the present invention, before step S102, the following steps are further included:
(1) acquiring a second request;
(2) and sending the random number and the first instruction to the communication object according to the second request.
Specifically, the communication object sends a second request to the device, and acquires the random number and the first instruction generated by the device.
S103, decrypting the first data through a second key to generate second data;
in combination with step S102, the second secret key is a public key corresponding to a private key in a legitimate communication object (a communication object matching with the device). It is understood that the first data generated by the legitimate communication object (communication object associated with the device) after encrypting the random number by the first key generates the second data under decryption by the second key, and the second data is consistent with the random number generated in step S101.
Specifically, in one embodiment of the present invention, the key pair of the RSA encryption algorithm is either fixed at the time of device production or burned into the device during development.
S104, generating a verification result according to the second data and the random number;
wherein the verification result comprises a first result and a second result.
S104 may be further divided into the following steps S1041-S1043:
step S1041, judging whether the second data is consistent with the random number;
specifically, according to steps S102 to S103, if the communication object is legal (communication object associated with the device), that is, if the communication object holds a private key paired with the second key (public key), the random number is encrypted by the first key at the communication object, and the second data obtained by decrypting the random number by the second key at the device side matches the random number generated in step S101. .
Step S1042, if yes, generating the first result, wherein the first result is that the verification is passed;
specifically, as shown in step S1041, if the second data matches the random number, the communication object passes the authentication.
And step S1043, if not, generating the second result, wherein the second result is that the verification is not passed.
Specifically, according to step S1041, if the second data is not consistent with the random number, the communication object authentication is not passed.
And S105, processing a second instruction according to the verification result.
Wherein the second instruction is a control instruction sent by the communication object.
S105 may be further divided into the following steps S1051-S1052:
step S1051, if the verification result is the first result, executing the second instruction;
specifically, if the communication object passes the verification, the device executes the control instruction sent by the communication object.
Step S1052, if the verification result is the second result, rejecting the second instruction.
Specifically, if the communication object fails to be verified, the device refuses to execute the control instruction sent by the communication object.
In summary, in the USB communication object verification method according to the embodiment of the present invention, the communication object is verified before the control instruction issued by the communication object is processed, so that the security of the device is improved, the information stored in the device is protected, and the behavior of the device is prevented from being tampered; by directly verifying the communication object, the instruction content issued by the communication object does not need to be subjected to targeted limitation, so that the flexibility is improved; the communication object is verified by generating the random number, encrypting the random number through the communication object and decrypting the random number ciphertext through the equipment end, no additional hardware is required to be introduced, the cost is reduced, the random numbers generated in each verification process are inconsistent, and the safety of the equipment is further improved.
