A New Family of Practical Non-Malleable Diffie-Hellman Protocols | | Andrew C. Yao

5 May 2011 | | Abstract: | Cryptography algorithm standards play a key role both to the practice and
engineering of information security and to cryptography theory research. Among
them, the MQV and HMQV protocols ((H)MQV, in short) are a family of
Diffie-Hellman key-exchange (DHKE) protocol that are widely standardized and
deployed. In this work, from some new perspectives and under some new design
insights and rationales, we present a new family of practical non-malleable
DHKE protocols, which enjoy notable performance among security, privacy,
efficiency and easy deployment. We make detailed comparisons between our new
DHKE protocols and (H)MQV, showing that our new protocols outperform HMQV in
most aspects. Along the way, guided by our new design rationales, we also
identify a new attack against (H)MQV. | | Source: | arXiv, 1105.1071 | | Services: | Forum | Review | PDF | Favorites | |
