ON REUSING EPHEMERAL KEYS IN DIFFIE-HELLMAN KEY AGREEMENT PROTOCOLS

by Alfred Menezes, Berkant Ustaoglu
"... Abstract. A party may choose to reuse ephemeral public keys in a Diffie-Hellman key agreement protocol in order to reduce its computational workload or to mitigate against denial-of-service attacks. In this note we highlight the danger of reusing ephemeral keys if domain parameters are not appropria ..."

Authenticated Diffie-Hellman Key Agreement Protocols

by Simon Blake-Wilson, Alfred Menezes , 1998
"... This paper surveys recent work on the design and analysis of key agreement protocols that are based on the intractability of the Diffie-Hellman problem. The focus is on protocols that have been standardized, or are in the process of being standardized, by organizations such as ANSI, IEEE, ISO/IEC, a ..."

Security Issues in the Diffie-Hellman Key Agreement Protocol

by Jean-françois Raymond, Anton Stiglic - IEEE Trans. on Information Theory , 2000
"... Diffie-Hellman key agreement protocol [27] implementations have been plagued by serious security flaws. The attacks can be very subtle and, more often than not, haven't been taken into account by protocol designers. In this paper we attempt to provide a link between theoretical research and r ..."

On the Relations Between Diffie-Hellman and ID-Based Key Agreement from Pairings

by Shengbao Wang , 2009
"... This paper studies the relationships between the traditional Diffie-Hellman key agreement protocol and the identity-based (ID-based) key agreement protocol from pairings. For the Sakai-Ohgishi-Kasahara (SOK) ID-based key construction, we show that identical to the Diffie-Hellman protocol, the SOK ke ..."

key agreement protocol also has three variants, namely ephemeral, semi-static and static versions. Upon this, we build solid relations between authenticated Diffie-Hellman (Auth-DH) protocols and ID-based authenticated key agreement (IB-AK) protocols, whereby we present two substitution rules

Analysis on the Diffie-Hellman Mode

by Riccardo Bresciani, Riccardo Bresciani , 2009
"... Abstract ZRTP is a key agreement protocol by Philip Zimmermann, Alan Johnston and Jon Callas, which relies on a Diffie-Hellman exchange to generate SRTP session parameters, providing confidentiality and protecting against Man-in-the-Middle attacks even without a public key infrastructure or endpoint ..."

Decidability for Lightweight Diffie-Hellman Protocols

by Daniel J. Dougherty, Joshua D. Guttman
"... Abstract—Many protocols use Diffie-Hellman key agreement, combined with certified long-term values or digital signatures for authentication. These protocols aim at security goals such as key secrecy, forward secrecy, resistance to key compromise attacks, and various flavors of authentication. Howeve ..."

Cryptanalysis and Improvement of an Elliptic Curve Diffie-Hellman Key Agreement Protocol ⋆

by Shengbao Wang, Zhenfu Cao, Maurizio Adriano Strangio, Lihua Wang , 2007
"... Abstract. In SAC’05, Strangio proposed protocol ECKE-1 as an efficient elliptic curve Diffie-Hellman two-party key agreement protocol using public key authentication. In this letter, we show that despite the author’s claims protocol ECKE-1 is vulnerable to key-compromise impersonation attacks. We al ..."

Exponentiation Speed Up For Diffie-Hellman Key Agreement Protocol

by Shay Gueron, Or Zuk , 2006
"... Abstract — The Diffie-Hellman key agreement protocol is a well known method in which two parties agree on a secret key by mean of public communication. From the computational point of view, the protocol requires, from both paries, to execute two exponentiations in some group, where the secret expone ..."
