This standard 21/30388926 DC BS ISO/IEC 20897-2. Information security, cybersecurity and privacy protection. Physically unclonable functions is classified in these ICS categories:

• 35.030 IT Security

This document specifies the test and evaluation methods for physically unclonable functions. The test and evaluation methods consist of inspection of the design rationale of the PUF and comparison between statistical analyses of the responses from a batch of PUFs or a unique PUF versus specified thresholds.

This document is related to ISO/IEC 19790 which specifies security requirements for cryptographic modules. In those modules, CSPs (key) and PSPs (ID) are the assets to protect. PUF is one solution to avoid storing security parameters, thereby increasing the overall security of a cryptographic module.
