NIST 800-171 v2
110 security requirements available
System and Communications Protection
Security Requirement
Employ FIPS-validated cryptography when used to protect the confidentiality of CUI.
Discussion
Cryptography can be employed to support many security solutions including the protection of controlled unclassified information, the provision of digital signatures, and the enforcement of information separation when authorized individuals have the necessary clearances for such information but lack the necessary formal access approvals. Cryptography can also be used to support random number generation and hash generation. Cryptographic standards include FIPS-validated cryptography and/or NSA-approved cryptography. See [NIST CRYPTO]; [NIST CAVP]; and [NIST CMVP].
