The design of efficient and secure lattice-based post quantum key exchange protocols has certain practical and theoretical significance. This paper proposed a scheme used straight-forward transformation LWE encryption mechanism and a ciphertext compression technology. This was a passively secure and practical key exchange protocol. Frodo was a key exchange scheme based on LWE problem proposed by Bos et al. which used the error reconciliation mechanism proposed by Peikert. The main advantage of the scheme over Frodo was simplicity. Compared with Frodo. the communications traffic merely increased by only 1.09%. reduced the complexity of the scheme effectively. It proved scheme to be passive security. which could resist quantum computer attacks. Compared with existing key exchange protocol based on learning with error, this protocol is very competitive.
