Abstract

The invention discloses a secret key management method. The method comprise: a secret key management controller running in a trusted execution environment receiving a secret key request sent by a userterminal; analyzing user information in the key request, and verifying whether the user terminal belongs to a registered user terminal or not according to the user information; and if the user terminal belongs to the registered user terminal, executing the key operation corresponding to the operator, so that the key management controller manages the key in a trusted execution environment, a safeand reliable key management controller is provided for the user terminal, the key is prevented from being leaked, and the security of the key is improved. On the other hand, the invention also discloses a key management controller and a key management system.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a key management method, controller and system. Background technique [0002] Keys are the basis of many data security technologies, such as signature verification of emails, identity authentication of remote servers, and encryption and decryption of cloud data, all of which require key participation. There are many existing key management schemes, and the commonly used ones are local storage, hardware device storage and server storage. However, these three schemes have their own limitations, which are analyzed as follows. [0003] Local storage: A method of storing keys on a local device for management. However, the key security of this method is low, and the key is easily stolen by malicious software on the local device, which leads to security problems in the process of using the key. [0004] Hardware device storage: a method of storing keys in dedicated hardware dev...
