The National Security Agency (NSA) released the “Commercial National Security Algorithm Suite 2.0” (CNSA 2.0) Cybersecurity Advisory (CSA) on September 7th to notify National Security Systems (NSS) owners, operators, and vendors of the future quantum-resistant (QR) algorithms requirements for NSS — networks that contain classified information or are otherwise critical to military and intelligence activities.

A cryptanalytically relevant quantum computer (CRQC) would have the potential to break public key systems (sometimes referred to as asymmetric cryptography) that are used today. Given foreign pursuits in quantum computing, now is the time to plan, prepare, and budget for a transition to QR algorithms to assure sustained protection of NSS and related assets in the event a CRQC becomes an achievable reality.
