The SetGroupPresharedKey method allows a management application to configure an initiator HBA to use the indicated preshared key whenever a key is required but no key is currently associated with the identifier (ID) for a session
When an initiator uses a preshared key in a key exchange, it associates the key with an identifier for the initiator and passes the identifier and its associated key to the target in the data portion of an identification packet (also known as the identification payload). The initiator passes the identifier and its associated key during phase 1 of an aggressive or main-mode Internet key exchange (IKE), as described in RFC 2407. 식별 페이로드는 대상이 안전한 방식으로 개시자를 식별하고 특정 개시자와의 연결에 적합한 보안 정책을 선택할 수 있도록 허용합니다.
The SetGroupPresharedKey method configures an initiator to use the default preshared key for identifiers that are not already associated with a key. To establish an explicit association between a key and a particular initiator identifier, a management application must call the SetPresharedKeyForId method. 식별자와 키 사이에 명시적 연결이 있는 경우 연결이 기본 키보다 우선하는 키입니다.
After the SetGroupPresharedKey method specifies the default key, the initiator should store this key in nonvolatile storage if nonvolatile storage is available. 그러나 초기자는 IKE 1단계 협상 중에 신속하게 사용할 수 있도록 키를 작업 메모리에 유지해야 합니다. 이렇게 하면 키 교환의 효율성이 향상됩니다.
SetGroupPresharedKey belongs to the unpublished MSiSCSI_SecurityConfigOperations WMI class. For a description of the parameters of the SetGroupPresharedKey method, see the member descriptions for the SetGroupPresharedKey_IN and SetGroupPresharedKey_OUT structures.
Miniport drivers that implement the MSiSCSI_SecurityConfigOperations WMI class must support SetGroupPresharedKey.
