With the rapid development of IoT technology, smart home is attracting much attention due to its convenience and comfort. In 2022, CHO et al. proposed an anonymous user authentication scheme using PUFs in smart home environment. However, this paper conducts a security analysis and finds that CHO et al.'s scheme cannot resist tracking attacks, replay attacks and cannot reach session keys. In order to overcome the shortcomings of CHO et al.'s scheme, this paper proposes an improved PUF-based secure anonymous user authentication scheme. After security analysis and comparison with related authentication schemes in terms of security and computational cost, it is demonstrated that the improved scheme is resistant to a variety of attacks and can achieve secure and efficient authentication.
