摘要: 针对智能家居中的事务委托场景,提出一种安全的委托认证方案,基于切比雪夫混沌映射分别构造适用于通用场景及委托场景的认证协议。考虑到切比雪夫映射的半群特性,所有标签与门禁阅读器共享唯一的认证服务器公钥,即可实现各实体之间的相互认证,解决了公钥密码认证方案中密钥管理繁琐的难题。利用BAN逻辑对所提方案正确性进行验证,并分析方案的安全性,结果表明,该方案安全可行,可以抗重放攻击和假冒攻击。

Abstract: Aiming at the situation of delegation in smart home,a secure authentication scheme is proposed,which constructs authentication protocols for general scene and delegation scene based on Chebeshev chaotic mapping.Since the Chebeshev chaotic mapping owns the semi-group property,only one public key of the trusted server is shared with all tags and readers to achieve mutual authentication between the entities,and the heavy key management is avoided which lies in the traditional public key based authentication.The correctness of the proposed scheme is verified by using the BAN logic,and the security is analyzed as well.Analysis results show that the proposed scheme is correct and secure,it can resist relay attacks and impersonation attacks.

Key words: Radio Frequency Identification(RFID), chaotic mapping, authentication, delegation, BAN logic
