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 to 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-assigned key pair to perform regular encryption and verification interactions 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 with 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...

Abstract

The invention discloses a wireless communication terminal and a method for binding the wireless communication with a user interface (UI). After being working normally, the wireless communication terminal and the UI perform periodic interaction of encryption verification with a preassigned key to verify the validity of the other side. With the technical solution of the invention, the one-to-one correspondence between a UI version and a data card software version is enhanced; the UI or data card can not be used normally when the UI version and the data card software version are not matched, and the requirement of an operator for achieving its special services by realizing the binding of the UI version and the data card software is satisfied. Meanwhile, the public key encryption algorithm, the encryption intensity of the algorithm and the time interval of verification can be modified on practical demands, so the practicability and confidentiality are greatly improved and the differentiated demands for various customizations are satisfied.

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...
