Information technology -- Security techniques -- Random bit generation
This standard was last reviewed and confirmed in 2017. Therefore this version remains current.
ISO/IEC 18031:2011 specifies a conceptual model for a random bit generator for cryptographic purposes, together with the elements of this model.
- specifies the characteristics of the main elements required for a non-deterministic random bit generator,
- specifies the characteristics of the main elements required for a deterministic random bit generator,
- establishes the security requirements for both the non-deterministic and the deterministic random bit generator.
Where there is a requirement to produce sequences of random numbers from random bit strings, ISO/IEC 18031:2011 gives guidelines on how this can be performed.
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 18031:2011.
