Password authented key exchange based on lattice for C/S model l&& Resistance to quantum computers

1.Research background

In view of the fact that the rapid development of quantum computer technology poses serious threat to the security of the traditional public-key cryptosystem, a new password authenticated key exchange protocol scheme based on Ring Learning With Errors (RLWE) problem was proposed. The results show that the proposed scheme is a more concise and efficient post quantum authenticated key exchange protocol.

2.Experiment result

If the client is computer，we can see this:

if the client is mobile phone ,we can see this:

3.conclusion

The results show that the proposed scheme is a more concise and efficient post quantum authenticated key exchange protocol.This is an effective and secure authented key exchange protocol and we believe it willl be benificial to the real world.
