Hi
I am trying to do a Quote operation.
when i create the aik key and use it for quote it works for me. But
when i try to load the Aik key from persistent storage, i am unable to
do a successful quote operation.
following is the code i am using :
LoadAik_and_Do_Quote() {
/***** srk - loading policies, setting secret ******/
TcBlobData srkSecret =
TcTssStructFactory.newBlobData().initString("tanish", false, "ASCII");
long srkSecretMode = TcTssDefines.TSS_SECRET_MODE_PLAIN;
TcIRsaKey srk =
context_.loadKeyByUuidFromSystem(TcUuidFactory.getInstance().getUuidSRK());
TcIPolicy srkPolicy = srk.getUsagePolicy(); /* default policy */
srkPolicy.setSecret(srkSecretMode, srkSecret);
/***** aik - setting policies,secret ******/
TcBlobData aikSecret =
TcTssStructFactory.newBlobData().initString("password", false,
"ASCII");
long aikSecretMode = TcTssDefines.TSS_SECRET_MODE_PLAIN;
TcIPolicy aikUsgPolicy =
context_.createPolicyObject(TcTssDefines.TSS_POLICY_USAGE);
/***** UUID to be called from storage : 1.2.3.4.5.010203040505 ******/
TcTssUuid aikUuid = null;
short array[] = {1,2,3,4,5,5};
aikUuid = TcTssStructFactory.newUuid().init(1, 2, 3, (short) 4,
(short) 5,array);
TcIRsaKey aikKey_ =
context_.getKeyByUuid(TcTssDefines.TSS_PS_TYPE_SYSTEM, aikUuid);
aikUsgPolicy.assignToObject(aikKey_);
TcIPolicy aikPolicy = aikKey_.getUsagePolicy();
aikUsgPolicy.setSecret(aikSecretMode,aikSecret);
aikKey_.loadKey(srk);
/******* quote ************/
TcIPcrComposite pcrs = context_.createPcrCompositeObject(0);
for (int i = 0; i < pcrList.length; i++) {
pcrs.selectPcrIndex(pcrList[i]);
}
TcTssValidation validation = TcTssStructFactory.newValidation();
validation.setExternalData(nonce);
// do the quote and return the resulting blob
validation = tpm.quote(aikKey_, pcrs, validation); // <----- Error line
}
==================================================
I get the following error :
TSPI call error:
error code: 0x01
error message: TPM layer: Authentication failed
at iaik.tss.impl.jni.TcBaseObject.handleRetCode(TcBaseObject.java:102)
at iaik.tss.impl.jni.TcTpm.quote(TcTpm.java:482)
at "Error line"
==================================================
i using correct passwords for srk and aik.
What may be going wrong ??
