| description | The invention discloses an ECDLP-based certificateless key management method and system, and belongs to the field of information security. According to the method, a certificateless public key cryptosystem and a certificateless key management mechanism which are based on an elliptic curve and do not use bilinear pairing operation are adopted, and system establishment, user key generation, user key use and cryptographic algorithm application are achieved. In the invention, the user has complete control right on the private key, the secret key can be revoked and regenerated, and the signature of the user has non-repudiation. The invention constructs a new certificateless key management system to realize distribution and management of user keys, including user registration, key generation, key updating, key revocation, public key identifier issuing and downloading, key state issuing and query and the like. The certificateless key management method and the certificateless key management system are a lightweight k |
