Abstract

The present invention discloses a cryptographic device and an implementation method thereof. A field programmable gate array system-level chip integrates an embedded ARM processor, and the field programmable gate array system-level chip is internally provided with a finite state machine; the ARM processor is connected with and communicates with the field programmable gate array system-level chip through an external memory interface; a nonvolatile flash memory is connected with the ARM processor and is configured to store firework programs, first secret keys and data of the ARM processor; and the finite state machine is connected with a plurality of cryptographic algorithm modules and a plurality of random number generators, the finite state machine is configured to schedule the cryptographic algorithm modules and the random number generators, and the random number generators are configured to generate true random numbers. The implementation method comprises the steps that: the ARM processor analyzes control instruction information and data to be decrypted received by the cryptographic device, determines whether the first secret keys are needed to be used or not, different secret keys are used in different conditions, and encryption and decryption operation and operation data transmission are completed.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular, to a cryptographic device and an implementation method. Background technique [0002] With the rapid development of communication and computer network technology, people are increasingly dependent on the network environment and network information resources, and the problem of network information security is becoming more and more serious. Network information crime has become a major hidden danger in today's society. Therefore, the storage of network information Effective protection of communication and transmission is the key to solving the above problems. [0003] The State Cryptography Administration has promulgated a variety of domestic cryptographic algorithms according to the needs of my country's information security. In order to support different cryptographic algorithms, it is necessary to design various cryptographic devices to meet the needs of diffe...
