Secure and Efficient Anonymous Authentication Key Agreement Scheme for Smart Industry

Real-time data access based on wireless sensor networks (WSNs) is an indispensable and essential foundation for real-time control of industrial processes, especially for the smart industry. But the transmission of real-time data between participants faces many security issues in WSNs, such as sensitive data leakage and unauthorized access. Many researchers have made efforts to solve such a problem. But there are no secure and efficient schemes because security schemes based on public key cryptography have excessive computation and communication cost, while non-public key security schemes are vulnerable to various security attacks. We design a secure and efficient anonymous authentication key agreement scheme to balance security and efficiency by combining physical unclonable function (PUF) and elliptic curve cryptography (ECC). It only uses simple cryptographic calculations to resist identity impersonation attacks based on PUF completely. It also achieves the consistency and randomness of the session key with only a small amount of ECC operations and can resist the attack of the session key. We present a formal security analysis based on Mao-Boyd logic and demonstrate that our scheme satisfies the security requirements for real-time data access in smart industry networks. And performance analysis shows that our scheme has a higher security level and also has greater advantages in terms of computation and communication cost.
