一种基于区块链的跨域认证密钥协商协议
Cross-Domain Authentication Key Agreement Protocol Based on Blockchain
摘要
Abstract
Combined with the advantages of blockchain such as traceability,asymmetric encryp-tion,and trusted transmission,this study proposes a cross-domain authentication model based on blockchain in the IoT environment,aiming to solve the network burden caused by the centralization of cross-domain authentication key agreement process.Secondly,the study proposes a cross-domain authentication key agreement protocol based on blockchain in the IoT environment.Through formal analysis,it is proved that the protocol meets the requirements of known session key security,for-ward security,and attributes resistance to key leakage attacks,and key compromise impersonation attack.The security of the protocol is proved under the eCK model.Finally,by comparing the se-curity attributes and computational efficiency of the protocol with other cross-domain authentication agreement protocols,it is found that the protocol can reduce the total computational,information transmission costs of IoT clients and smart contract invocation time while ensuring communication security,achieving a balance between security performance and communication consumption.关键词
