Generic and Efficient Lattice-Based Key Exchange from Key Consensus with Noise

摘要

Lattice-based cryptography is promising in the post-quantum era. For cryptographic usage, compared with the classic hard lattice problems such as SVP and CVP, the learning with errors (LWE) problem and its variants are proven to be much more versatile. Based upon them, a large number of impressive works are developed in recent years, with key exchange (KE) as the focus of this work.
