论文摘要
在这项工作中,我们详细讨论了Winternitz一次性签名方案的W-OTS $ {^+} $变体的原始安全证明的缺陷,这是各种无状态和州基于许多基于哈希的数字签名方案的重要组成部分。我们更新W-OTS $ {^+} $方案的安全性证明,并得出相应的安全级别。我们的结果对于基于哈希的数字签名方案的安全分析至关重要。
In this work, we discuss in detail a flaw in the original security proof of the W-OTS${^+}$ variant of the Winternitz one-time signature scheme, which is an important component for various stateless and stateful many-time hash-based digital signature schemes. We update the security proof for the W-OTS${^+}$ scheme and derive the corresponding security level. Our result is of importance for the security analysis of hash-based digital signature schemes.
