| Name | Data Type | Value |
| AHTransformId | uint16 | |
| Description | string | AHTransformId is an enumeration that specifies the hash algorithm to be used. The list of values was generated from RFC2407, Section 4.4.3. |
| MappingStrings | string | IPSP Model.IETF|AHTransform.AHTransformID, RFC2407.IETF|Section 4.4.3 |
| ModelCorrespondence | string | CIM_AHTransform.OtherAHTransformId |
| ValueMap | string | 1, 2, 3, 4 |
| Values | string | Other, MD5, SHA-1, DES |
| OtherAHTransformId | string | |
| Description | string | Description of the hash algorithm when the value 1 ("Other") is specified for the property, AHTransformId. |
| ModelCorrespondence | string | CIM_AHTransform.AHTransformId |
| ReplayPreventionWindowSize | uint32 | |
| Description | string | ReplayPreventionWindowsSize specifies, in bits, the length of the sliding window used by the replay prevention mechanism. The value of this property is meaningless if UseReplayPrevention is false. The window size MUST be a power of 2. |
| MappingStrings | string | IPSP Model.IETF|AHTransform.ReplayPreventionWindowSize |
| Units | string | Bits |
| UseReplayPrevention | boolean | |
| Description | string | UseReplayPrevention causes the local peer to enable replay prevention detection. This can be accomplished by using a sequence number when sending a packet or checking the sequence number upon receipt of a packet. |
