Weakness and simple improvement of anonymous mutual authentication protocol with link-layer
Heasuk Jo, Seungjoo Kim, Dongho Won · 2012
In mobile communication environment, mutual authentication is very important. Lu et al. proposed an anonymous mutual authentication protocol with provable link-layer location privacy. In this paper, we identify a flaw in their design and demonstrate that the Lu et al. protocol is vulnerable to the QoS (Quality of Service) of a packet's sending/receiving state and to DoS (Denial of Service) attack. We then propose a method for improving the protocol. We hope that through this analysis of flaws in the protocol, similar structural mistakes can be avoided in future designs, similar structural mistakes can be avoided in future designs.
