A Fast Identity Authentication Solution for the Sensing Layer in Internet of Things

Trusted access to the Internet of Things sensing layer node is the precondition for the trusted operation of the Internet of Things. How to quickly and accurately implement identity authentication of a sensing node is currently a research hotspot. After comprehensive consideration of the security requirements and functional requirements of the sensing Node Identity Authentication, this paper proposes a fast identity authentication scheme for sensing nodes. In the identification process of sensing nodes, the data aggregation node is responsible for the selection of system parameters and the registration of sensing nodes. It does not directly participate in the authentication process and simplifies the authentication process. The computational efficiency is high, and the security analysis shows that the scheme has forward security and can resist malicious attacks such as replay attacks, key information disclosure attacks, and forgery attacks. Also, the solution supports key updates. Computational complexity analysis shows that this protocol uses only a small amount of computational complexity in exchange for higher security and more features.
