_WWAN_AUTH_SIM_RESPONSE structure

Description

The WWAN_AUTH_SIM_RESPONSE structure represents a response to a SIM authentication challenge.

Members

`n`

The number of responses.

`Kc1`

Encryption key 1 of 64 bit. This member represents a multi-byte value in little-endian format.

`Kc2`

Encryption key 2 of 64 bit. This member represents a multi-byte value in little-endian format.

`Kc3`

Encryption key 3 of 64 bit. This member represents a multi-byte value in little-endian format.

`Sres1`

Response 1 of 32 bit. This member represents a multi-byte value in little-endian format.

`Sres2`

Response 2 of 32 bit. This member represents a multi-byte value in little-endian format.

`Sres3`

Response 3 of 32 bit. This member represents a multi-byte value in little-endian format.

Remarks

The n member can be either 2 or 3, according to RFC 4186. If it is set to 2, use the Sres1/Kc1 and Sres2/Kc2 members. If it is set to 3,use Sres1/Kc1, Sres2/Kc2, and Sres3/Kc3 members.

The WWAN_AUTH_RESPONSE structure uses this structure.
