TpmChangeAuthAsymStart

public static java.lang.Object[] TpmChangeAuthAsymStart(TcIStreamDest dest,
                                                        long idHandle,
                                                        TcTpmNonce antiReplay,
                                                        TcTpmKeyParms tempKey,
                                                        TcTcsAuth inAuth1)

                                                        TcTpmException

Parameters:

dest - The destination where the byte stream is written to.

inAuth1 - Authorization values for first authorization session.

idHandle - The keyHandle identifier of a loaded identity ID key

antiReplay - The nonce to be inserted into the certifyInfo structure

tempKey - Structure contains all parameters of ephemeral key.

Returns:

The returned Object[] holds the following elements:

• 0 ... TPM return code (Long)
• 1 ... outgoing authorization for session containing new nonceEven (TcTpmAuth)
• 2 ... The certifyInfo structure that is to be signed. (TcTpmCertifyInfo)
• 3 ... The signature of the certifyInfo parameter. (TcBlobData)
• 4 ... The keyHandle identifier to be used by ChangeAuthAsymFinish for the ephemeral key (long)
• 5 ... Structure containing all parameters and public part of ephemeral key. TcTpmKey.encSize is set to 0. (TcTpmKey)

Throws:

TcTpmException - This exception indicates that a TPM error has occurred. The specific error code id held by the exception.

entityType - The type of entity to be modified

newAuthLink - HMAC calculation that links the old and new AuthData values together

encNewAuth - New AuthData encrypted with ephemeral key.

encData - The encrypted entity that is to bemodified.

Returns:

The returned Object[] holds the following elements:

• 0 ... TPM return code (Long)
• 1 ... outgoing authorization for session containing new nonceEven (TcTpmAuth)
• 2 ... The modified, encrypted entity. (TcBlobData)
• 3 ... A nonce value from the TPM RNG to add entropy to the changeProof value (TcTpmNonce)
• 4 ... Proof that AuthData has changed. (TcTpmDigest)

Throws:

TcTpmException - This exception indicates that a TPM error has occurred. The specific error code id held by the exception.
