Public key exchange protocol is identified as an important application in the field of public-key cryptography. Most of the existing public key exchange schemes are Diffie-Hellman (DH)-type, whose security is based on DH problems over different groups. Note that there exists shor's polynomial-time algorithm to solve these DH problems when a quantum computer is available, the authors are therefore motivated to seek for a non-DHtype and quantum resistant key exchange protocol. To this end, they turn their attention to lattice-based cryptography.
