Problems solved by technology

The elliptic curve cryptosystem is the system with the highest encryption strength per bit among the known public key cryptosystems; however, its mathematical theory is very profound and complicated, and it is difficult to realize in engineering applications, but its unit security strength is relatively higher
One of the characteristics of the RSA public key cryptographic algorithm is that its mathematical principle is simple and it is relatively easy to implement in engineering applications, but its unit security strength is relatively low

Embodiment Construction

[0032] The invention provides a wireless communication terminal and a method for binding it with a UI.

[0033] The principle of realizing the corresponding binding is that after the wireless communication terminal and the UI work normally, they use the pre-allocated key pair to perform regular encryption verification interaction to verify the correctness of the other party and ensure the one-to-one correspondence between the UI and the wireless communication terminal. , to achieve mutual binding.

[0034]The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. In this embodiment, the wireless communication terminal is described by taking a data card as an example.

[0035] Such as figure 1 and figure 2 As shown, a schematic diagram of the encryption and decryption process from the data card board side to the UI side and from the UI side to the board side using the public key encryption algorithm in the pr...

Abstract

The invention relates to a wireless communication terminal and a method thereof for binding with a UI. The terminal comprises a plate attention (AT) command processing module, a plate public secrete key computation module and a plate control module, wherein the plate AT command processing module is used for receiving an AT command from the UI and transmitting the AT command to the UI; the plate public secrete key computation module is used for securely storing a public key and using the public key to conduct encryption and decryption functions; and the plate control module completes the coordination and control of all the plate modules. By using the technical scheme of the invention, the correspondence between a UI version and a data card software version is strengthened; and when the UI version and the data card software version are not matched, the UI and a data card cannot be used normally, so that the requirement of an operator on the realization of special services by binding the UI version and the data card software version is met.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, to a wireless communication terminal and a method for binding it to a UI (User Interface). Background technique [0002] With the development of wireless communication technology, a wireless communication terminal, especially a data card, has become an important mobile terminal device, which is more and more widely used at the present stage. UI (User Interface) is the PC-side software for the data card to interact with the user. Data card-related services, such as phonebook, Internet access, SMS, MMS, voice call service, video call service, etc., interact with the user through the UI. Then the UI interacts with the data card through standard AT commands and some extended AT commands of the data card, and the data card implements these services. In the implementation scheme of the data card, the UI plays a very important role. [0003] In order to be...
