INITIALIZATION


TEST PROCEDURE

  This test check is following.

AGGRESSIVE EXCHANGE
# Initiator(TN) Direction Responder(NUT) (1) HDR; SA, KE, Ni, IDii ========>
(2) <======== HDR; SA, KE, Nr, IDir, HASH_R Judgement (Check *1)
1. Send the first message from TN 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). Keying material used to arrive at a common shared secret and random information which is used to guarantee liveness and protect against replay attacks are also transmitted. Additionally, the initiator transmits identification information.
2. Receive the second message from NUT In the second message (2), the responder indicates the protection suite it has accepted with the Security Association, Proposal, and Transform payloads. Keying material used to arrive at a common shared secret and random information which is used to guarantee liveness and protect against replay attacks is also transmitted.Additionally, the responder transmits identification information and the results of the agreed upon authentication function(hash function).


JUDGEMENT

        The first message must be accepted. 
        And the second message that has only one proposal(3DES:5,SHA:2,PSK:1,DH2:2) 
        and Transform # field = 2 must be returned.
        And must conform to above Configuration.


TERMINATION

  Clean up SAD and SPD


REFERENCE

  RFC2408
  4.1.1 Notation

(omit)
SA is an SA negotiation payload with one or more Proposal and Transform payloads. An initiator MAY provide multiple proposals for negotiation; a responder MUST reply with only one.
(omit)
4.2 Security Association Establishment
(omit)
The Transform payload provides the initiating entity with the capability to present to the responding entity multiple mechanisms, or transforms, for a given protocol. The Proposal payload identifies a Protocol for which services and mechanisms are being negotiated. The Transform payload allows the initiating entity to present several possible supported transforms for that proposed protocol. There may be several transforms associated with a specific Proposal payload each identified in a separate Transform payload. The multiple transforms MUST be presented with monotonically increasing numbers in the initiator's preference order. The receiving entity MUST select a single transform for each protocol in a proposal or reject the entire proposal. The use of the Transform number in multiple Transform payloads provides a second level OR operation, i.e. Transform 1 OR Transform 2 OR Transform 3. Example 1 below shows two possible transforms for ESP and a single transform for AH. Example 2 below shows one transform for AH AND one transform for ESP OR two transforms for ESP alone. Note that the Next Payload field of the Transform payload points to another Transform payload or 0. The Proposal payload delineates the different proposals.
When responding to a Security Association payload, the responder MUST send a Security Association payload with the selected proposal, which may consist of multiple Proposal payloads and their associated Transform payloads. Each of the Proposal payloads MUST contain a single Transform payload associated with the Protocol. The responder SHOULD retain the Proposal # field in the Proposal payload and the Transform # field in each Transform payload of the selected Proposal. Retention of Proposal and Transform numbers should speed the initiator's protocol processing by negating the need to compare the respondor's selection with every offered option. These values enable the initiator to perform the comparison directly and quickly. The initiator MUST verify that the Security Association payload received from the responder matches one of the proposals sent initially.

RFC2409 3.2 Notation
(omit)
SA is an SA negotiation payload with one or more proposals. An initiator MAY provide multiple proposals for negotiation; a responder MUST reply with only one.
(omit)
7.1 Phase 1 using Main Mode
The following diagram illustrates the payloads exchanged between the two parties in the first round trip exchange. The initiator MAY propose several proposals; the responder MUST reply with one.
