N2 - The demand of exchanging information among various fields raises concerns in cross-domain user authentication concerns. Most of the current authentication schemes rely on trusted third-party platforms for centralized operations, resulting in information isolation or single point of failure. In order to realize the secure and efficient identity authentication of users in cross-domain process, we propose a safety-liveness probability consensus scheme based on decentralized identity. We use the notary group as the trust relationship between different domains, and obtain the minimum notary group size through the safety-liveness dichotomy technology, thereby improving the efficiency of the system consensus. In addition, the memory consensus protocol is also used to ensure the smooth progress of the consensus process. Experiments show that compared with the BFT-SMaRt scheme, the cross-domain authentication scheme has good security and operational efficiency, and has high availability in practical applications.
