Crypto Quantique offers free randomness test for PUFs
Cyber security company Crypto Quantique Ltd. (London, England) is offering a randomness test suite for physical unclonable functions (PUFs) as a free GitHub download.
The suite is called Turing and enables the testing of PUFs used in semiconductors for secure random number generation. These numbers underpin device security, providing the basis for unique device identities and cryptographic key generation.
Unlike traditional Random Number Generators (RNGs), PUFs produce a fixed-length output, making existing tests inadequate for determining randomness, said Crytpo Quantique. Such tests are fundamental to secure device root-of-trust (RoT). The Turing test suite adapts existing tests from the NIST 800-22 suite, making them suitable for the unique characteristics of PUFs, such as spatial dependencies and limited output length.
Crypto Quantique’s Turing open-source test suite is available as a free GitHub download at https://github.com/cryptoquantique/puf-randomness-test, from where a detailed technical white paper can also be downloaded.
