Key management system, method, device and equipment

Abstract

The embodiment of the invention provides a key management system, method, device and equipment. The system comprises a server used which is used for obtaining a to-be-processed application, generating a transferable root key based on the to-be-processed application, and sending the transferable root key to at least one client corresponding to the to-be-processed application; and at least one client which is in communication connection with the server, and is used for obtaining the migratable root key, determining a to-be-processed application corresponding to the migratable root key, and performing encryption management on a data key of the to-be-processed application based on the migratable root key. According to the technical scheme provided by the embodiment of the invention, hardware does not need to be added on a system, and key management is realized through a software module, so the key management cost is effectively reduced; besides, the use mode of the system is flexible and reliable, and various different key management information can be supported, so the system has expandability and is convenient to maintain and manage, and the key management quality and efficiency are effectively ensured.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a key management system, method, device and equipment. Background technique [0002] Cryptography technology is an important technical basis for protecting the safe, stable and efficient operation of information systems, and one of the core technologies of cryptographic technology for key management. In the prior art, it is generally necessary to use a hardware cryptographic module to implement key management. Although this cryptographic management method has high security, the cost of cryptographic management is also high and the maintainability is poor. SUMMARY OF THE INVENTION [0003] The embodiments of the present invention provide a key management system, method, device and equipment, which can ensure the quality and efficiency of password management, and also have the characteristics of low cost, good compatibility and high maintainability. [0004] In a...
