  • Verification Points
      IKE implementations support the following attribute values
      Parameter Value
      ISAKMP SA Attributes - 3DES in CBC mode
      - SHA
      - Authentication via pre-shared keys.
      - MODP over group number fourteen.
      So, IKE implementations support DH14.

Algorithms for Internet Key Exchange version 1 (IKEv1)
draft-hoffman-ikev1-algorithms-02.txt
3.  New algorithm requirements


   The new requirements for IKEv1 are:


   o  TripleDES for encryption MUST be supported
   o  AES-128 in CBC mode [RFC3602] SHOULD be supported
   o  SHA-1 for hashing and HMAC functions MUST be supported
   o  Pre-shared secrets for authentication MUST be supported
   o  AES-128 in CBC mode for HMAC functions ([RFC3566] and [RFC3664])
      SHOULD be supported
   o  Diffie-Hellman MODP group 2 (discrete log 1024 bits) MUST be
      supported
   o  Diffie-Hellman MODP group 14 (discrete log 2048 bits) [RFC3526]
      SHOULD be supported
   o  RSA for authentication with signatures SHOULD be supported


   The other algorithms that were listed at MUST-level and SHOULD-level
   in RFC 2409 are now MAY-level.  This includes DES for encryption, MD5
   and Tiger for hashing, Diffie-Hellman MODP group 1, Diffie-Hellman
   MODP groups with elliptic curves, DSA for authentication with
   signatures, and RSA for authentication with encryption.  DES for
   encryption, MD5 for hashing, Diffie-Hellman MODP group 1 are dropped
   to MAY due to cryptographic weakness.  Tiger for hashing,
   Diffie-Hellman MODP groups with elliptic curves, DSA for
   authentication with signatures, and RSA for authentication with
   encryption are dropped due to lack of any significant deployment and
   interoperability.
