英文摘要	Public Key Infrastructure (PKI) technology is a widely used identity authentication technology. This paper uses blockchain technology to improve it and implements decentralized PKI authentication, which resolves the issues in the traditional PKI such as single point of failure and certificate transparency. However, most of the current research uses the method of traversing the blockchain to query the certificate (identity, public key) to realize identity authentication, which is inefficient. And as the size of blockchain continues to grow, storage overhead is growing. In this paper, we combine the blockchain and the dynamic accumulator to construct a blockchain PKI model that can batch update certificates, which improves the efficiency of identity authentication. The model can effectively add, revoke and update user certificates. Meanwhile, this paper builds a one-stop PKI authentication service model based on blockchain, Through the certificate blockchain, we can provide one-stop user authentication service to third-party service providers. Finally, we verify the security and effectiveness of the scheme. © 2020, Springer Nature Singapore Pte Ltd.
