FIPS 140-2 Compliant Algorithms

Question

Is there any reference to check the list of encryption & signing algorithms which are compliant to FIPS 140-2. After an exhaustive search I could find only "AES".

Any suggestions would be much appreciated.

Answer 1

Take a look at FIPS 140-2 Annex A. It lists the following:

• Symmetric Key
  • AES, Triple-DES, Escrowed Encryption Standard
• Asymmetric Key
  • DSA, RSA, ECDSA
• Hash Standards
  
  • SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256
• Random number generators
  • See annex c
• Message authentication
  • CCM, GCM, GMAC, CMAC, HMAC

Answer 2

The current list of FIPS-approved cryptographical methods is here.

For encryption, we're limited to AES, 3DES (known as TDEA in FIPS-speak), and EES (Skipjack).

As for signing algorithms, we have RSA, DSA and ECDSA.

Note that the list of FIPS-approved algorithms does change at times; not extremely frequently, but more often than they come out with a new version of FIPS 140.
