摘要
The present invention primarily relates to the field of information security technology, and specifically relates to a novel decentralized public key management method and trust model, the method being constructed on a distributed data network platform like blockchain or P2P, ensuring each node of the platform is capable of participating in maintaining full life cycle management of a user public key, and recording a every status change in a user public key during a life cycle in ledger form. The present method can add public key records which have passed verification to a consistent public key storage structure of a platform to be saved; all public key records of the same user may be arranged from first to last in order of time to generate a public key log chain, and an authentication chain and a trust network may be formed based on a recommender signature; efficient public key search may be implemented based on a user identifier. The present invention ensures convenient and accurate issuance and acquisition of a user public key, ensures an acquired public key is valid, correct, consistent, and not deceptive, and can act as infrastructure to support authentication, encryption, integrity and accountability services.
