示例1: AIKChallengeResponse
// AIKChallengeResponse takes the output from GenerateChallenge along with the
// encrypted AIK key blob. The TPM then decrypts the asymmetric challenge with
// its EK in order to obtain the AES key, and uses the AES key to decrypt the
// symmetrically encrypted data. It verifies that this data blob corresponds
// to the AIK it was given, and if so hands back the secret contained within
// the symmetrically encrypted data.
func AIKChallengeResponse(context *tspi.Context, aikblob []byte, asymchallenge []byte, symchallenge []byte) (secret []byte, err error) {
var wellKnown [20]byte
srk, err := context.LoadKeyByUUID(tspi.TSS_PS_TYPE_SYSTEM, tspi.TSS_UUID_SRK)
if err != nil {
return nil, err

srkpolicy, err := srk.GetPolicy(tspi.TSS_POLICY_USAGE)
