A quantum-resistant cryptography algorithm, HAWK, which was being considered as a potential US standard, has been withdrawn after a flaw was identified by an Anthropic security model. HAWK is a digital signature scheme intended to be resilient against future quantum computer attacks. It had passed two rounds of testing by the National Institute of Standards and Technology (NIST) as part of its evaluation of post-quantum cryptographic algorithms. HAWK was undergoing a third round of testing aimed at identifying such vulnerabilities when the flaw was uncovered. Following the announcement by Anthropic on Monday, the developer of HAWK stated on Tuesday that he would be withdrawing the algorithm from consideration.

HAWK Algorithm Withdrawn from Consideration After Flaw Discovered
The HAWK algorithm, a candidate for US standardization in quantum-resistant cryptography, has been withdrawn after a flaw was discovered by Anthropic's security model. It had previously passed two rounds of testing by NIST and was in a third round aimed at identifying vulnerabilities.
