  HAWK post-quantum signature scheme withdrawn after flaw found

  HAWK, a post-quantum digital signature scheme under review for possible US standardization, has been withdrawn after a flaw was identified. The issue was found with help from Anthropic's security model during the third NIST evaluation round, which is designed to expose exactly these kinds of weaknesses.

  Claude finds new weaknesses in HAWK and reduced-round AES

  Anthropic says Claude Mythos Preview autonomously discovered improved attacks against two cryptographic targets: the post-quantum digital signature scheme HAWK and a reduced-round version of AES. The findings do not affect deployed production systems, but they show AI models can help uncover mathematical flaws in cryptographic algorithms, not just implementation bugs.

  Why ambulance rides in the U.S. are so expensive

  The article examines why emergency ambulance rides in the United States often lead to large surprise bills, even for insured patients. It argues that the problem is driven less by simple greed than by a flawed billing and reimbursement system, especially for out-of-network ground ambulances that remain exempt from federal surprise-billing protections.

  White House Post-Quantum Order Sets Federal Migration Deadlines

  The White House signed Executive Order 14412 to accelerate the U.S. government’s move to post-quantum cryptography, setting deadlines for agencies and contractors to adopt post-quantum encryption and authentication. Cloudflare says the order is an important milestone and notes that migration to post-quantum encryption is already underway, while post-quantum authentication is just beginning.
