摘要
承诺方案是构造现代密码学中大部分协议的核心工具。给出了离散无记忆噪声信道模型中的一种带交互的比特承诺方案,引入哈希函数,从信息理论安全的角度介绍了比特承诺的速率和容量,并分析了方案的安全性能。
A trusted protocol for committing a classical bit could be used for protocols implementing a wide range of other cryptographic tasks. This paper discusses a safe bit commitment scheme over noisy Channels, which imports one-way hash function and interaction. It introduces the commitment capacity and analyses the security performance of the scheme studied from an information-theoretic perspective.
