Sarr, Philippe Elbaz-Vincent & Jean-Claude Bajard Conference paper 1350 Accesses 41 Citations Part of the Lecture Notes in Computer Science book series (LNSC,volume 6280) Abstract WebDiffie–Hellman Key Exchange (DHKE) is a cryptographic method to securely exchange cryptographic keys (key agreement protocol) over a public (insecure) channel in a way that overheard communication does not reveal the keys. The exchanged keys are used later for encrypted communication (e.g. using a symmetric cipher like AES).

WebAbstract. This paper proposes an efficient two-pass protocol for authenticated key agreement in the asymmetric (public-key) setting. The protocol is based on Diffie-Hellman key agreement and can be modified to work in an arbitrary finite group and, in particular, elliptic curve groups. Two modifications of this protocol are also presented: a ... Webscheme.
