NTRUSign based wireless authentication and key agreement protocol
LV Shan-wei · Computer Engineering and Applications Journal · 2009
NTRU is a low cost and fast public key cryptosystem,which is suit to resource constraint applications.NTRUSign is a novel digital signature scheme,which is base on NTRU.A new wireless authentication and key agreement protocol using NTRUSign is also proposed.The security of the protocol relies on the fact that for most lattices,it is very difficult to find extremely short vectors.The protocol has three phases:user registration phase,server registration phase,authentication and key agreement phase.Furthermore,after analyzing the security and performance of the protocol,the proposed protocol is a better scheme with lower cost and strong security.
