Information technology — Security techniques — Random bit generation

Scope

This document specifies a conceptual model for a random bit generator for cryptographic purposes, together with the elements of this model.
This document specifies the characteristics of the main elements required for both non-deterministic and deterministic random bit generators. It also establishes the security requirements for both non-deterministic and deterministic random bit generators.
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 this document.
