Secure access implementation method applying terminal access intelligent card

Abstract

The invention discloses a secure access implementation method applying a terminal access intelligent card, which includes: arranging a security module in the intelligent card; and arranging an intelligent card access program, an input-output device and a communication module at an application terminal, wherein the security module comprises a key, a data encryption and decryption algorithm and a process program, the data encryption and decryption algorithm is used for realizing a security function, the process program is used for processing application logic and data in the process of secure access, the intelligent card access program is used for providing an interface interacting with the security module, the input-output device is used for interacting with the security module, and the communication module is used for realizing data communication of the security module with a background of the application terminal. As the security module capable of realizing secure access process is arranged in the intelligent card, data related to security do not run at the application terminal of a user, and security of secure access is improved.

Description

technical field [0001] The invention relates to the field of data security, in particular to a method for implementing secure access for an application terminal to access a smart card. Background technique [0002] A smart card is a chip card with an embedded memory and a microprocessor, which stores and calculates data through the embedded microprocessor. At present, banking, communication, transportation and other systems have obtained the security and flexibility that other systems do not have by using the characteristics of smart cards. Because the smart card has a convenient storage function, can store data in the form of cipher text, and can use the embedded microprocessor to encrypt and decrypt data, the appearance of the smart card has greatly improved the convenience and security of access. Nowadays, some security-critical applications often use the characteristics of smart cards to enhance security and reduce risk factors. [0003] In the prior art, although smar...

Problems solved by technology

[0004] In the prior art, there is still a hidden danger of leakage of sensitive data in the process of safe access such as electronic transactions when it is processed on POS terminals and application terminals such as PCs, and the data security between the smart card and the back-end system cannot be guaranteed, so , the current security system for security device applications is not perfect enough to achieve true end-to-end security
