Abstract:

With the rapid development of quantum computing technology, password-authenticated key exchange (PAKE) protocol based on conventional difficult problems will face serious security threats in the post-quantum era.Lattice-based cryptosystem has been certified by NIST as the most promising cryptosystem in the post-quantum era due to its high efficiency, high security and support for stronger cryptographic service functions (such as fully homomorphic encryption and multi-linear mapping).Firstly, the research progress of lattice-based PAKE protocol was systematically sort out, mainly including the centralized two-party, three-party PAKE protocol and the distributed PAKE protocol over lattices.Then, the relevant typical schemes were compared and analyzed, respectively.Finally, the future research directions PAKE protocol over lattices were prospected.

Key words: password-authenticated key exchange, lattice, provably secure, quantum resistance
