Improved data synchronization method and system for cryptographic equipment

Abstract

The present invention relates to an improved data synchronization method and system of a cryptographic device. The method includes: the management board receives instructions from the management channel, manages permissions and keys according to the instructions, and updates the data in the storage space of the management board; The data in its own storage space is synchronized to the data distribution center module; the management board sends an update command to the online computing board, and the computing board receives the command and obtains the data in the data distribution center module and stores it in its own storage space; the computing board receives data from the computing channel command; each computing board responds to and feeds back the command of the computing channel according to the updated data; end. The invention improves the performance while taking into account the protection of data, so as to ensure that sensitive data will not enter the memory of the host. In the scheme, the flexible resource of FPGA is used to realize the function of data collection and distribution center.

Description

technical field [0001] The invention relates to an improved data synchronization method and system of a cryptographic device, belonging to the technical field of information security. Background technique [0002] PKI, that is, public key infrastructure, is a key management platform that follows established standards. It can provide cryptographic services such as encryption and digital signatures and the necessary key and certificate management systems for all network applications. Simply put, PKI It is a technical facility that uses public key theory and technology to provide security services. PKI technology is the core of information security technology, and also the key and basic technology of e-commerce. The basic technology of PKI includes encryption, digital signature, data integrity mechanism, digital envelope, double digital signature and so on. [0003] In the field of PKI application, it is generally divided into terminal and server. [0004] The terminal produ...
