Cryptographic application security construction based on commercial cryptographic application standards
The domestic commercial cryptographic technology is the core technology to ensure the security of business information systems,and that is related to the security of important system data.This article mainly introduces the domestic commercial cryptographic algorithms and working modes.In combination with the technical index requirements of third level in GB/T 39786-2021"Information Security Technology-Baseline for Information System Cryptography Application",a simulation application system that meets the requirements of identity authentication,confidentiality and integrity of important data transmission and storage,as well as anti-repudiation function is established locally.The solutions based on commercial cryptographic technology are provided for each technical level.
