Abstract

Decentralized public key infrastructure based on blockchain abandons certificate authority. With authoritativeness and publicity of the blockchain, this infrastructure is able to implement decentralized identity authentication. Many researches chose to traverse the entire blockchain to look up for a specific ID-PK pair and then verify whether the public key belongs to someone who claims it. However, this method is obviously inefficient. This paper proposed an identity authentication method based on cryptographic accumulators, which map identity, public key and auxiliary information to one accumulated value. This method improved the authentication efficiency, especially when current blockchain was large. In addition, it solved the problem that lightweight clients do not had enough storage capacity when the size of blockchain was continuously increasing. It also carried out some experiments to measure this method. It verifies its feasibility and correctness.
