OPAQUE - An Asymmetric PAKE Protocol Secure Against Pre-computation Attacks

Explore an asymmetric Password-Authenticated Key Exchange (PAKE) protocol called OPAQUE, designed to be secure against pre-computation attacks. Delve into the motivation behind password authentication, examine password protocols in cryptographic literature, and understand PAKE in the client-server setting. Investigate pre-computation attacks and compare state-of-the-art PAKE solutions with password-over-TLS practices. Learn about OPAQUE's contributions, performance metrics, features, and its integration with TLS. Discover various extensions of the OPAQUE protocol in this informative conference talk presented at Eurocrypt 2018.
