SUMMARY:School Seminar Series
DESCRIPTION:Jintai Ding: Post-quantum cryptography – a New Era.\n\nPublic key cryptosystems (PKC) are the security foundation of modern communication systems, in particular, the Internet. However Shor's algorithm shows that the existing PKC like Diffie-Hellmann key exchange, RSA and ECC can be completely broken by a powerful 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 will present an introduction to post-quantum cryptography and its recent developments, in particular, the NIST standardization process and its impact. Then we will present a practical and provably secure key exchange protocol based on the learning with errors problems, which is conceptually simple and has strong provable security properties. This new construction was established in 2011-2012. We will explain that all the existing LWE-based key exchanges are variants of this fundamental design. We will finally present the challenges facing the post-quantum migration.\n\nhttps://www.csc.liv.ac.uk/research/seminars/abstract.php?id=1276
