A Lightweight Authentication Protocol for Network Security Based on PUF
摘要
This paper analyses the protocol Wang Li et al. designed and points out the protocol security problem; based on the protocol framework, we propose an improved lightweight authentication protocol for resisting exhaustive attacks. The proposed protocol uses ultra-lightweight byte synthesis operation and PUF function instead of Hash and PUF function to encrypt information, which can control the computation amount while ensuring security. The byte synthesis operation fully uses the Hamming weight parameter of the encrypted information and combines the different information bits to disrupt the attacker's exhaustive attack. From the aspect of security and computation, it is shown that the proposed protocol can resist impersonation attacks and exhaustive attacks, and the calculation amount can be accepted in strictly restricted low-cost tags.
