Abstract: 通过构造不可延展的、可提取的且是弱模拟可靠的陷门承诺体制,以及相应的平滑投射Hash函数簇,设计了一个高效的通用可组合(universal composable,简称UC)安全的两方口令认证密钥交换(password authenticated key exchange,简称PAKE)协议,并在静态腐化模型下给出了严格的安全性证明.该协议使得PAKE协议在UC框架下达到了最优的两轮.与已有的协议相比,该协议避免了零知识证明协议的使用,在保持计算复杂度相当的前提下有效地提高了通信效率.
English Abstract: Through constructing and utilizing non-malleable, extractable, and weak simulation-sound trapdoor commitment schemes and corresponding smooth projective hash function familes, this paper proposes an efficient two-party password authenticated key exchange (PAKE) protocol within the universal composable (UC) framework, which is the optimal two-round PAKE protocol in this setting. Rigorous security proofs based on standard assumptions in the presence of static corruption adversary are then given out. Comparisons with previously proposed protocols show that, this protocol avoids the use of zero-knowledge protocols, and achieves a higher performance in terms of communication efficiency while attaining a comparable computational complexity. © Copyright 2011, Institute of Software, the Chinese Academy of Sciences.
