Abstract
This paper proposes a new and 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 one-pass authenticated key agreement protocol suitable for environments where only one entity is on-line, and a three-pass protocol in which key confirmation is additionally provided. The protocols are currently under consideration for standardization in ANSI X9.42 [2], ANSI X9.63 [4] and IEEE P1363 [18]. Keywords: Diffie-Hellman, authenticated key agreement, key confirmation, elliptic curves. An Efficient Protocol for Authenticated Key Agreement 1 1 Introduction Key establishment is the process by which two (or more) entities establish a shared secret key. The key is subsequently used to achieve some cryptographic goal such as confidentiality or d...
