The length of the response in the Res member.

`Auts`

A 112-bit value generated by the peer upon a synchronization failure. This member is valid only in case of failure. This member represents a multi-byte value in little-endian format.

`CKP`

The ciphering key. This member is valid only in case of success. This member represents a multi-byte value in little-endian format.

`IKP`

The integrating key. This member is valid only in case of success. This member represents a multi-byte value in little-endian format.

`Res`

A 128-bit authentication result from the peer, which, together with the RAND, authenticates the peer to the server. This member is valid only in case of success. This member represents a multi-byte value in little-endian format.
