As an important application of the Internet of Things, smart home has greatly facilitated our life. Since the communication channels of smart home are insecure and the transmitted data are usually sensitive, a secure and anonymous user authentication scheme is required. Numerous attempts have been taken to design such authentication schemes. Recently, Shuai et al. (Computer & Security 86(2019):132146) designed an anonymous authentication scheme for smart home using elliptic curve cryptography. They claimed that the proposed scheme is secure against various attacks and provides ideal attributes. However, we show that their scheme cannot resist inside attack and offline dictionary attack and also fails to achieve forward secrecy. Furthermore, we give some suggestions to enhance the security of the scheme. These suggestions also apply to other user authentication schemes with similar flaws.

“可证明安全的智能家居环境的匿名认证方案”的安全性分析

智能家居作为物联网的重要应用,极大地便利了我们的生活。由于智能家居的通信通道不安全,并且传输的数据通常是敏感的,因此需要一种安全且匿名的用户身份验证方案。已经进行了许多尝试来设计这样的认证方案。最近,帅等。(Computer&Security 86(2019):132146)使用椭圆曲线密码学设计了一种用于智能家居的匿名身份验证方案。他们声称,提出的方案可抵抗各种攻击,并提供理想的属性。但是,我们表明,他们的方案无法抵抗内部攻击和离线字典攻击,并且也无法实现前向保密。此外,我们提出一些建议,以提高该计划的安全性。
