Description

A remote control verification method on a mobile Internet device

technical field

The present invention relates to the field of mobile Internet equipment technology and remote control verification technology, in particular to a remote control verification method on a mobile Internet device.

Background technique

With the development of computer networks and the popularization of wireless networks, people can already connect to computer networks anytime and anywhere in many places. In the coming 3G era, the scope of people's use of computer networks will be greatly expanded. People's life, work and entertainment are increasingly inseparable from computer networks. Through computer networks, people can use computers to conduct online meetings, browse the web, watch movies and TV, and conduct online transactions. The increase of wireless computer network access points and the abundance of applications make traditional network terminals represented by desktop computers less and less able to adapt to the new network environment. The traditional way to connect to a computer network is to use a personal computer. However, the desktop personal computer cannot meet the needs of people surfing the Internet anytime and anywhere due to its large size and heavy weight. The notebook computer can make mobile Internet access possible. However, mainstream notebook computers still have some shortcomings in weight and volume, and some portable notebooks are more expensive. At the same time, a mobile phone with an Internet access function is also an available terminal, but the general performance and expandability of the mobile phone are poor. Therefore, mobile Internet devices are proposed to solve these problems.

Mobile Internet device MID is a mobile device that can connect to the Internet through a wireless Internet access point, which provides new possibilities for mobile Internet connection terminals. Mobile Internet equipment is a portable mobile computer terminal based on the existing computer architecture. Because it is based on the existing computer architecture and is consistent with the traditional computer architecture, it has good scalability and performance, and has good mobility and endurance. However, due to the limitation of heat dissipation system and battery life, the performance of mobile Internet devices is still not as good as that of traditional computers. Due to the limited computing power of the mobile Internet device, some applications running on the mobile Internet device will be restricted by the processing capability of the mobile Internet device. In order to solve this problem and improve the application capabilities of mobile Internet devices, remote control is applied to mobile Internet devices.

Remote Control is a network application that will be divided into client and server. It sends control signals from the client to the server, changes the behavior of the server, and sends the results of the server back to the client in the form of graphics. Remote control involves many aspects such as user verification and data verification, and requires strict and effective verification methods.

Verification refers to confirming the legitimacy of users and data through certain methods. Authentication is found in a variety of domains, both as a common security mechanism and as a method that underlies many security mechanisms. At present, there are many existing mechanisms for authentication, and the key-based mechanism is one of the more common types.

Public key infrastructure (PKI) is an infrastructure for ensuring communication confidentiality, identity authentication and identification, information leakage prevention, and information integrity assurance in computer networks. The central idea of PKI is to use the public key cipher system PKC to encrypt and decrypt information.

In PKC, the key is a group of two, called the public key and the private key. Data encrypted with the private key can be decrypted with the public key, and data encrypted with the public key can be decrypted with the private key. Due to the particularity of the algorithm, the public key can be easily obtained from the private key, but it is difficult to obtain the private key from the public key. In PKI, the public key is provided by the issuer to the users who need to authenticate the issuer. The private key is owned only by the publisher and is used to encrypt the message.

Description of drawings

Accompanying drawing is the implementation process schematic diagram of the present invention.

Detailed ways

The present invention will be further described below in conjunction with drawings and embodiments.

The implementation process of the present invention as shown in the accompanying drawings is as follows:

1) Provide identity information to the remote server:

According to the user's input, the mobile Internet device provides identity information to the remote server. The identity information includes a user port and a user password. The port is recorded as Porm, and the password is recorded as Pasm. Both of these pieces of information are entered by the user and will be sent from the mobile internet device to the remote server over the internet. The following table is an example of the identity information (Port1, Pas1) sent to the remote server Server1:

remote server name port name password Server1 Port1 Pas1

The first column above is the remote server name, the second column is the port name of the remote server, and the third column is the password.

2) The remote server verifies the identity information:

After the remote server receives the identity information provided by the mobile Internet device, it verifies the identity information. After the verification is successful, it returns the public key corresponding to the Porm obtained from the remote key store, and the key is recorded as Keym.

An example of the information stored in the remote keystore of the remote server Server1 is as follows:

port name password public key private key Port1 Pas1 Key1 PKey1 Port2 Pas2 Key2 PKey2 Port3 Pas3 Key3 PKey3 Port4 Pas4 Key4 PKey4

The first column above is the port name, the second column is the password, the third column is the public key, and the fourth column is the private key.

After receiving the identity information (Port1, Pas1), the remote server Server1 first searches for the password Pas1 corresponding to Port1, and finds a match, then searches for the public key Key1 corresponding to Port1, and sends it to the mobile Internet device.

At the same time, the public key and private key pair stored in the remote key store has a characteristic, that is, the key Keym and PKeym corresponding to the same port. For the control signal Keym-Inputn obtained by using Keym to encrypt the user input Inputn, if using PKeym to decrypt, will get the user input Inputn itself. For example, in the above example, the public key Key1 and the private key PKey1 are the public key and private key pair corresponding to the same port. After encrypting a user input Input1 with Key1, a control signal Key1-Input1 is obtained. If you decrypt using PKey1 for Key1-Input1, you will get user input Input1.

3) Establish a remote control connection:

After receiving the public key Keym, the mobile Internet device uses the key to establish a remote control connection with the remote server, and puts the public key Keym into the key store AK of the mobile Internet device.

Taking the mobile Internet device receiving the above-mentioned public key Key1 as an example, the mobile Internet device will use Key1 to establish a remote control connection with the remote server Server1, and add items to the key store AK. An example of AK is as follows:

remote server name port name public key Server3 Port2 Key2 Server2 Port3 Key3 Server1 Port4 Key4 Server1 Port1 Key1

The first column above is the name of the remote server, the second column is the port name of the remote server, and the third column is the public key.

The fourth line is the newly added item in the above example. A mobile Internet device can store the public keys sent by multiple remote servers, and classify the remote servers through the first remote server name in the key store; it can also store the public keys corresponding to multiple ports of a remote server , identified by the second port name of the keystore.

4) Send control signal:

After establishing a remote control connection with the remote server, the mobile Internet device sends a control signal to the remote server when the user inputs, and the user input is recorded as Inputn. Taking Input1 input by the user and the corresponding input port being Port1 as an example, a detailed description is given.

The first step is to convert the user's input to the corresponding user port Porm, and take out the corresponding public key Keym from the key store. In the example, the port corresponding to the user's input is Port1. In the key store AK, it can be found that the public key corresponding to Port1 is Key1, and the public key Key1 is taken out from the key store.

In the second step, use the public key Keym to encrypt Inputn, and record the result as Keym-Inputn. In the example, since the user input to be encrypted is Input1, and the previously obtained public key is Key1, the mobile Internet device will use Key1 to encrypt Input1, and a new control signal will be obtained after encryption, which is Key1-Input1.

In the third step, the encrypted user input Keym-Inputn is sent to the remote server. In an example, the mobile Internet device sends the control signal Key1-Input1 to the remote server Server1 through the Internet.

5) The remote server verifies the control signal:

When the remote server receives the control signal Keym-Inputn of the user port Portm, it uses the private key PKeym corresponding to the user port to decrypt the control signal to complete the verification of the remote control. In the example, after receiving the control signal Key1-Input1 sent by the mobile Internet device through the user port Port1, the remote server Server1 will verify the control signal.

The first step is to obtain the private key PKeym corresponding to the user port Portm from the remote key store. In the example, the remote server Server1 will receive the control signal Key1-Input1 sent by the mobile Internet device from the user port Port1, and then look up the private key corresponding to the user port Port1 from its remote key store, which is PKey1.

The second step is to use the private key PKeym to decrypt the control signal Keym-Inputn to obtain the user input Inputn. In the example, the remote server will use the private key PKey1 obtained in the previous step to decrypt the control signal Key1-Input1. Since Key1 and Pkey1 are a pair of public key and private key corresponding to the same port, the user input Input1 will be obtained after decryption.

The third step is to verify Inputn and complete the remote control verification. In the example, the remote server will check the user input Input1 to ensure that Input1 is the correct executable user input.

At this point, the verification of the remote control from the mobile Internet device is completed.
