| Summary: | Password-based three-party authenticated key exchange protocol allow clients to establish a protected session key through a server over insecure channels.Most of the existing PAKE protocols on lattices were designed for the two parties,which could not be applied to large-scale communication systems,so a novel three-party PAKE protocol from lattices was proposed.The PAKE protocol was constructed by using a splittable public-key encryption scheme and an associated approximate smooth projective Hash function,and message authentication mechanism was introduced in the protocol to resist replay attacks.Compared with the similar protocols,the new protocol reduces the number of communication round and improves the efficiency and the security of protocol applications. |
