Building strong security and good efficiency authentication scheme is the key to ensuring the security of distribution system.NTRUSign is a low cost and fast signature scheme,which suits to resource constraint applications.A new remote user authentication scheme using password and NTRUSign is also proposed.The scheme has three phases:registration phase,authentication phase and password changing phase.The security of the scheme relies on Hash function and the fact that for most lattices,it is very difficult to find extremely short vectors.Furthermore,the scheme has many merits:it lets users freely choose and change password at their own will;it provides mutual authentication between two entities;it resists man-in-middle attack and denial of service attack;in addition,it has forward security and strong security reparability.In a word,the proposed scheme is a better scheme with lower cost and stronger security,which can be applied in high security level environment.
