A high-security encryption and decryption operation ability expansion method and system

Abstract

The invention discloses a high-security encryption and decryption operation ability expansion method and a system. The method comprises the following steps: a main processor transmits the data to be encrypted and decrypted and the program call of the encryption and decryption operation to a FPGA main controller through system communication; the FPGA main controller receives the relevant data and caches the data; the FPGA main controller decomposes the program call into a series of sub-procedures, and generates the corresponding command call sequence and data packet for the operations involvingthe security chip. The FPGA main controller sends corresponding command calls and related data to a plurality of security chips, and each security chip feeds back the operation results to the FPGA master. The FPGA main controller aggregates the results from all the security chips and sends the final results to the main processor. The FPGA main controller comprises a high-security application program, a micro-kernel operating system and a multi-core CPU. The invention greatly improves the security protection capability against the security chip.

Description

technical field [0001] The invention relates to the technical field of security chips, in particular to a method and system for expanding high-security encryption and decryption computing capabilities. Background technique [0002] A security chip refers to an integrated circuit chip that implements one or more cryptographic algorithms and uses cryptographic techniques directly or indirectly to protect keys and sensitive information. As the bottom-level security guarantee of smart terminals, the application of security chips can effectively prevent hacker attacks and cracks, improve the security of smart terminals, and protect users' personal information and application data security. At present, security chips are increasingly being used in smart terminals to provide reliable protection for financial payment and online identity authentication. The security chip is a trusted platform module. It is a device that can independently generate keys and encrypt and decrypt. It has...

Problems solved by technology

[0010] That is to say, in the prior art, there is a problem that the encryption and decryption computing capability of the security chip itself is low, and at the same time, the operating environment of the traditional security chip cannot effectively expand the high security encryption and decryption computing capability due to insufficient security protection capabilities.
