CNSS Advisory Memo on Use of Public Standards for Secure Sharing of Information Among NatSec Systems 08/11/15 <https://t.co/O2h82B5ZGE>https://www.cnss.gov/CNSS/openDoc.cfm?DLuhIVBMUGJh7R8iXAWwIQ== This Advisory expands on the guidance contained in CNSS Policy No. 15, National Information Assurance Policy on the Use of Public Standards for the Secure Sharing of Information Among National Security Systems (Reference a). Based on analysis of the effect of quantum computing on Information Assurance (IA) and IA-enabled Information Technology (IT) products, the policy's set of authorized algorithms is expanded to provide vendors and IT users more near-term flexibility in meeting their IA interoperability requirements. The purpose behind this additional flexibility is to avoid vendors and customers making two major transitions in a relatively short timeframe, as we anticipate a need to shift to quantum-resistant cryptography in the near future.
