标准摘要
[中文适用范围]： 本文件通过附录规定了状态数字签名机制，其中安全级别由底层哈希函数的安全属性决定。本文件还提供了实施基本状态管理的要求，这对于安全部署本文件中描述的状态方案是必需的。 [外文原描述]： This document specifies stateful digital signature mechanisms with appendix, where the level of security is determined by the security properties of the underlying hash function. This document also provides requirements for implementing basic state management, which is needed for the secure deployment of the stateful schemes described in this document.
英文名称Information security - Digital signatures with appendix - Part 4: Stateful hash-based mechanisms
