Post Quantum Key Exchange based on the learning with errors problems
Presenter: Jintai Ding (U. of Cincinnati)
Public key cryptosystems (PKC) are critical part of the foundation of modern communication systems, in particular, Internet. However Shor’s algorithm shows that the existing PKC like Diffie-Hellmann key exchange, RSA and ECC can be broken by a quantum computer. To prepare for the coming age of quantum computing, we need to build new public key cryptosystems that could resist quantum computer attacks. In this lecture, we present a practical and provably secure (authenticated) key exchange protocol based on the learning with errors problems, which is conceptually simple and has strong provable security properties. Several concrete choices of parameters are provided, and a proof-of-concept implementation shows that our protocols are indeed practical.
In addition, we will show how to use the signal function invented for KE for authentication schemes.
