一种新的基于秘密子群生成器的可证安全密钥协商

A Novel Provably Secure Key-Agreement Using Secret Subgroup Generator

Abdelhaliem Babiker

摘要:

本文提出并分析了一种新的密钥协商方案。除了在共享秘密密钥不可否认性模型下可证明安全外,该方案还有一个有趣的功能::在使用循环子群上的幂运算建立密钥协商的同时,隐藏了该循环子群的生成元,从而使方案能够抵抗能够解决离散对数问题的对手,这意味着该方案可能成为后量子密钥交换方案的候选者.

英文摘要:

In this paper, a new key-agreement scheme is proposed and analyzed. In addition to being provably secure in shared secret key indistinguishability model, the scheme has an interesting feature: while using exponentiation over a cyclic subgroup to establish the key-agreement, the generator of that subgroup is hidden to secure the scheme against adversaries that are capable of solving the Discrete Logarithm Problem, which means that the scheme might be candidate as a post-quantum key exchange scheme.
