A Multi-Blockchain-Based Cross-Domain Authentication and Authorization Scheme for Energy Internet

The expansion of the scale Power Internet Things stimulated by development Energy makes growth in demand for effective authentication and access control technologies cross-domain data exchange. Based on cross-chain technology blockchain cuckoo filter, this paper proposes a scheme Things. Firstly, architecture is established. Combined with existing used intra-domain authentication, process based proposed to realize automatic transmission credentials from application domain domain. filter deployed as smart contracts, user certificate fingerprint inserted into registration, query, revocation, which reduces cost management. Experimental results show effectiveness feasibility our scheme. scheme, roles object classes presented, treating controlled objects then applying role-based classes, condition that heterogeneous domains have same kinds resources.
