<VulnDiscussion>Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect classified data. The application must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated. Advanced Encryption Standard (AES) Symmetric block cipher used for information protection FIPS Pub 197 Use 256 bit keys to protect up to TOP SECRET Elliptic Curve Diffie-Hellman (ECDH) Key Exchange Asymmetric algorithm used for key establishment NIST SP 800-56A Use Curve P-384 to protect up to TOP SECRET. Elliptic Curve Digital Signature Algorithm (ECDSA) Asymmetric algorithm used for digital signatures FIPS Pub 186-4 Use Curve P-384 to protect up to TOP SECRET.
