[Trustedjava-support] Auth Session closed by TPM

[Ronald P. <rpe...@ma...>]

Hi,

when I try to read the SRK public key from my TPM via jtss I get the error code "0x30c4" (The auth session has been closed by the TPM. The provided auth session is not loaded in the TPM and is not cached. It might have been evicted (from TPM and/or cache) due to space limitations.)

Has someone else encountered this problem as well?

All other TPM access works fine (e.g. reading PCRs, generating random numbers,...) but when it comes to user authorization this problem occurs. I am using the password that I have set when taking the ownership with tpm.msc (Windows 7).

Thanks a lot in advance and best regards,
Ronald
