[0003] The management method of the security policy in the prior art is to set various solutions in each security policy, and to select and manage various stored security policies through a visual operation interface, so as to solve the algorithm key library switching And the updated problem, the storage medium adopted by the storage module of the security policy described in the above prior art is a magnetic disk, an optical disk, a read-only storage memory or a random storage memory, but the data information cannot meet the requirements of high security

A security policy configuration method is also disclosed in the prior art, which is to establish a security policy table according to each security element, use the determined security level and the current scene to determine the required algorithm protocol, and obtain the algorithm protocol in the security policy table, it can be seen that , the security level, current scene and algorithm protocol used in the security strategy of this method are all in a determined state, and its algorithm protocol is easily identified by attackers and leads to adverse consequences such as data information being intercepted, tampered with, forged, etc., and the security is relatively high.
