Title:
KEY MANAGEMENT METHOD, KEY MANAGEMENT APPARATUS, KEY MANAGEMENT DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/236397
Kind Code:
A1
Abstract:
The present application is applicable to the technical field of security management, and specifically discloses a key management method, a key management apparatus, a key management device and a non-volatile readable storage medium. A multi-node key storage system is built; key data is stored in a random node in the multi-node key storage system when the key data required by an encryption/decryption service procedure is not in a use state, and the migration of the key data between nodes in the multi-node key storage system is controlled according to a preset migration rule, instead of directly storing the key data in a memory corresponding to the encryption/ decryption service procedure, so that an attacker cannot know the storage location of the key data, and thus it is difficult to steal the key data by means of existing attack means; and when a key calling request based on the encryption/decryption service procedure is received, the storage location of the key data at the current moment can be determined on the basis of the preset migration rule to feed back the key calling request.
