Commercial National Security Algorithm Suite
The Commercial National Security Algorithm Suite is a set of cryptographic algorithms promulgated by the National Security Agency as a replacement for NSA Suite B Cryptography algorithms. It serves as the cryptographic base to protect US National Security Systems information up to the top secret level, while the NSA plans for a transition to quantum-resistant cryptography.[1][2][3][4][5][6][7]
The suite includes
- Advanced Encryption Standard with 256 bit keys
- Elliptic-curve Diffie–Hellman and Elliptic Curve Digital Signature Algorithm with curve P-384
- SHA-2 with 384 bits, Diffie–Hellman key exchange with a minimum 3072-bit modulus, and
- RSA with a minimum modulus size of 3072.[2]
