Security and efficiency are the two main challenges for designing a smart home system. In this paper, by incorporating Chinese remainder theorem (CRT) into the elliptic curve Diffie–Hellman (ECDH), a lightweight key agreement protocol for smart home systems is constructed. Firstly, one-way hash authentication is used to identify the sensor nodes instead of mutual authentication to reduce the authentication cost. Secondly, the CRT is introduced to enhance the security of the original ECDH key agreement. Security analysis showed that the proposed protocol can validate the data integrity and resist the replay attack, the man-in-middle attack, and other attacks. Performance analysis and experiments showed that the protocol achieves high security with low communication and computation costs, and can be implemented in smart home systems.

Abstract Vehicle ad hoc network (VANET) is an open communication environment. Any user can broadcast messages, which means that it can be easily attacked by malicious users. Therefore, the authentication of vehicles is needed. In this paper, we propose a Chebyshev polynomial-based conditional privacy-preserving authentication and group-key agreement scheme for VANET. Specifically, we solve three problems in VANET: (1) we improve the effectiveness of TA by using Chebyshev polynomial to authenticate vehicles; (2) we reduce the computational burden of TA by using Chinese remainder theorem to manage group members; (3) we provide conditional privacy for users by using traceable pseudonym scheme. Theoretical and experimental results show that the proposed scheme is more efficient than existing related work.
