数联网环境下基于秘密共享的移动数据终端切换认证方案
Handover authentication scheme for mobile data terminal based on secret sharing in the data Internet
摘要
Abstract
To address authentication delays and security issues caused by mobile data terminals in the data internet environ-ment,a handover authentication scheme based on secret sharing was proposed.The concept of interoperability domains was introduced,and a Markov process was employed to predict node trust states.Nodes with similar trust levels were dy-namically aggregated into logical subdomains sharing authentication information,reducing global authentication to local cooperation within subdomains.For high-trust interoperability domains,the secret-sharing property of bivariate symmetric polynomials was exploited to pre-distribute authentication credentials within each subdomain,enabling terminals to com-plete handover authentication using only their secret shares.Centralized authentication was thereby transformed into edge authentication among intra-domain nodes,pushing the authentication center down to the edge.The security of the scheme was formally verified using the Tamarin tool,and its computational and communication overheads were evaluated.Results show that the proposed scheme is suitable for highly dynamic access environments in the data Internet.关键词
