  • Article

3/26/2014

This structure specifies a single security association (SA).

Syntax

typedef struct _OFFLOAD_SECURITY_ASSOCIATION {
  OFFLOAD_OPERATION_E  Operation;
  SPI_TYPE  SPI;
  OFFLOAD_ALGO_INFO  IntegrityAlgo;
  OFFLOAD_ALGO_INFO  ConfAlgo;
  OFFLOAD_ALGO_INFO  Reserved;
} OFFLOAD_SECURITY_ASSOCIATION, *POFFLOAD_SECURITY_ASSOCIATION;

Members

  • Operation
    The Internet Protocol security (IPsec) operation for which the SA is to be used. The following operations are supported:

    • AUTHENTICATE
      The SA will be used for authentication (integrity checking).
    • ENCRYPT
      The SA will be used for encryption/decryption (confidentiality).
  • SPI
    The Security Parameters Index (SPI) for the SA.
  • IntegrityAlgo
    The integrity (authentication) algorithm for the SA, formatted as an OFFLOAD_ALGO_INFO structure.
  • ConfAlgo
    The confidentiality (encryption/decryption) algorithm for the SA, formatted as an OFFLOAD_ALGO_INFO structure.
  • Reserved
    Reserved.

Remarks

The OFFLOAD_SECURITY_ASSOCIATION structure is used with the OID_TCP_TASK_IPSEC_ADD_SA and OID_TCP_TASK_IPSEC_ADD_UDPESP_SA OIDs.
