Hello, i solved the problem by desactivating the checkReply option (lowLevel.setCheckReply(false)) but i don't know how important is that the checkReply option is enabled. I'm trying to do a remote platform attestation. ----- Original Message ----- From: "Andrés Rosado Laitinen" <and...@te...> To: <tpm...@li...> Sent: Sunday, April 22, 2007 9:34 AM Subject: [Tpm4java-users] Problem using GenerateAIKrequest > Hello, i receive an error using the example class GenerateAikrequest. > I'm using linux with tpm-emulator-0.5 this is the error message that i > receive: > > Expected: A0 CD BE 29 EC B3 3B B1 51 CB C1 1F 93 0B AB F3 > 21 26 9C 7C > TPM send: 3B 03 84 5A 67 A4 A3 1B 61 85 7E E4 F9 02 66 93 > 31 04 F9 7D > java.lang.RuntimeException: de.datenzone.tpm4java.TSSException: reply > authentication failed > at > de.datenzone.tpm4java.TssHighLevelImpl.generateAIK(TssHighLevelImpl.java:130) > at > de.datenzone.tpm4java.examples.GenerateAikRequest.main(GenerateAikRequest.java:95) > Caused by: de.datenzone.tpm4java.TSSException: reply authentication > failed > at > de.datenzone.tpm4java.TSSCoreService.verifyReplyHmac(TSSCoreService.java:2127) > at > de.datenzone.tpm4java.TSSCoreService.authGetAndVerify(TSSCoreService.java:2178) > at > de.datenzone.tpm4java.TSSCoreService.authGetAndVerify(TSSCoreService.java:2184) > at > de.datenzone.tpm4java.TSSCoreService.TPM_LoadKey(TSSCoreService.java:685) > at > de.datenzone.tpm4java.TssHighLevelImpl.generateAIK(TssHighLevelImpl.java:126) > ... 1 more > > > > ------------------------------------------------------------------------- > This SF.net email is sponsored by DB2 Express > Download DB2 Express C - the FREE version of DB2 express and take > control of your XML.

Hello Andrés, all checkReply does is verifying if the hmac of the tpm reply is correct. This is done to prevent a replay attack or modifications by a man-in-the-middle between the program and the tpm. Practically there is no problem if you turn this option off. Other tpm libraries even omit the verification by default.

Hello, i've got a problem using the funtion "activateAik", it bring me = =3D an error. I'm trying to realize a remote platform attestation. I guess = =3D that i can decrypt the ca response without using the TPM but i'm not =3D sure.
