标准摘要
[中文适用范围]: 本国际标准规定了用于加密目的的随机位生成器的概念模型以及该模型的元素。 本国际标准还包括以下内容: ?非确定性随机位生成器所需的主要元素的描述; ?确定性随机位生成器所需的主要元素的描述; ?他们的特点; ?他们的安全要求。 如果需要从随机位串生成随机数序列,附件 B 提供了如何执行此操作的指南。 用于独立验证或确认的随机位生成器统计测试技术以及此类生成器的详细设计不属于本国际标准的范围。 [外文原描述]: ISO/IEC 18031:2005 specifies a conceptual model for a random bit generator for cryptographic purposes, together with the elements of this model. ISO/IEC 18031:2005 also includes the description of the main elements required for a non-deterministic random bit generator;the description of the main elements required for a deterministic random bit generator;their characteristics; their security requirements. Techniques for statistical testing of random bit generators for the purposes of independent verification or validation, and detailed designs for such generators, are outside the scope of ISO/IEC 18031:2005.
