一族新的实用不可延展Diffie-Hellman协议

A New Family of Practical Non-Malleable Diffie-Hellman Protocols

Andrew C. Yao, Yunlei Zhao

摘要:

密码算法标准对信息安全实践和密码学理论研究都起着至关重要的作用。其中,MQV和HMQV协议(简称(H)MQV)是广泛标准化和部署的(隐式认证)Diffie-Hellman密钥交换(DHKE)协议族。在这项工作中,从一些新的角度和方法,并在一些新的设计理念和见解,我们开发了一个新的家庭的实用隐式认证DHKE协议,具有显着的性能之间的安全性,隐私性,效率和易于部署。我们对新的DHKE协议和(H)MQV协议进行了详细的比较,表明新开发的协议在许多方面优于HMQV。在此过程中,在我们新的设计原理的指导下,我们还确定了一个新的漏洞(H)MQV,它带来了一些新的观点(例如,计算公平性)。

英文摘要:

Cryptography algorithm standards play a key role both to the practice of information security and to cryptography theory research. Among them, the MQV and HMQV protocols ((H)MQV, in short) are a family of (implicitly authenticated) Diffie-Hellman key-exchange (DHKE) protocols that are widely standardized and deployed. In this work, from some new perspectives and approaches and under some new design rationales and insights, we develop a new family of practical implicitly authenticated 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 the newly developed protocols outperform HMQV in most aspects. Along the way, guided by our new design rationales, we also identify a new vulnerability (H)MQV, which brings some new perspectives (e.g., computational fairness) to the literature.
