Description
Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. The ALG must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated. NIST cryptographic algorithms are approved by NSA to protect NSS. Based on an analysis of the impact of quantum computing, cryptographic algorithms specified by CNSSP-15 and approved for use in products in the CSfC program have been changed to more stringent protocols configure with increased bit sizes and other secure characteristics to protect against quantum computing threats. The Commercial National Security Algorithm Suite (CNSA Suite) replaces Suite B. This requirement also applies to Zero Trust initiatives.
