Re: [Tpm4java-users] testing tpm4java for remote attestation

[Frederic S. <st...@se...>]

Both PCR values and Nonce are used to compute the signature. I suggest
that you look at the tpm4java API specification and in particular at the
TPMSignedData class. You also find detailed information on the the
detailed structure of the signature in the TCG specification. You can
download it on

Cheers,
Frederic
