  • Verification Points
        When communication is protected, all payloads following the ISAKMP
        header MUST be encrypted.
    	
  • Configuration
    •        
    • Initiator and Responder IKE parameter
    • At least, following parameter must be included in proposal.

  This test check is following.

IDENTITY PROTECTION EXCHANGE
# Initiator(NUT) Direction Responder(TN) (1) HDR; SA ========>
(2) <======== HDR; SA
(3) HDR; KE; NONCE ========>
(4) <======== HDR; KE; NONCE
(5) HDR*; IDii; HASH_I ========> <---must be encrypted Judgement (Check *1)
1. Receive the first message from NUT In the first message (1), the initiator generates a proposal it considers adequate to protect traffic for the given situation. The Security Association, Proposal, and Transform payloads are included in the Security Association payload (for notation purposes).
2. Send the second message from TN In the second message (2), the responder indicates the protection suite it has accepted with the Security Association, Proposal, and Transform payloads.
3. Receive the third message from NUT In the third (3) message, the initiator send keying material used to arrive at a common shared secret and random information which is used to guarantee liveness and protect against replay attacks.
4. Send the fourth message from TN In the fourth (4) message, the responder send keying material used to arrive at a common shared secret and random information which is used to guarantee liveness and protect against replay attacks.
5. Receive the fifth message from NUT In the fifth (5) message, the initiator send identification information and the results of the agreed upon authentication function(hash function).
=end html =head1 JUDGEMENT The first to the fourth message must be exchanged correctly. The fifth message must be encrypted and received. And must conform to above Configuration. =head1 TERMINATION Clean up SAD and SPD =head1 REFERENCE =begin html
  RFC2408 
  3.1 ISAKMP Header Format

(omit)
o Flags (1 octet) - indicates specific options that are set for the ISAKMP exchange. The flags listed below are specified in the Flags field beginning with the least significant bit, i.e the Encryption bit is bit 0 of the Flags field, the Commit bit is bit 1 of the Flags field, and the Authentication Only bit is bit 2 of the Flags field. The remaining bits of the Flags field MUST be set to 0 prior to transmission.
-- E(ncryption Bit) (1 bit) - If set (1), all payloads following the header are encrypted using the encryption algorithm identified in the ISAKMP SA. The ISAKMP SA Identifier is the combination of the initiator and responder cookie. It is RECOMMENDED that encryption of communications be done as soon as possible between the peers. For all ISAKMP exchanges described in section 4.1, the encryption SHOULD begin after both parties have exchanged Key Exchange payloads. If the E(ncryption Bit) is not set (0), the payloads are not encrypted.
(omit)
RFC2409 3.2 Notation
(omit)
Message encryption (when noted by a '*' after the ISAKMP header) MUST begin immediately after the ISAKMP header. When communication is protected, all payloads following the ISAKMP header MUST be encrypted. Encryption keys are generated from SKEYID_e in a manner that is defined for each algorithm.
