Authentication Scheme Based on Alliance Chain Cross-System
Juanjuan Xu, Caihua Qiu · 2023
At present, many solutions solve the cross-domain identity authentication scheme of cryptosystem, but cannot realize the entity heterogeneous cross-domain authentication between PKI and CLC users. In this regard, this paper proposes a cross-domain authentication identity scheme for heterogeneous members in the consortium chain, which uses the characteristics of blockchain, such as decentralization, trust, and traceability and tamper resistance. The model uses the blockchain certificate server and verification server to realize cross-domain authentication between users of heterogeneous systems, and the authentication algorithm meets the efficient identity authentication protocol. Compared with other schemes in terms of security and authentication efficiency, this method reduces the computational authentication overhead, simplifies the heterogeneous cross-domain authentication model, and realizes the secure and efficient cross-domain authentication of heterogeneous members.
