Re: [Trustedjava-support] How to use the command "TPM_EstablishTransport"

[Ronald T. <ron...@ia...>]

Hello Shohei,

I am very sorry, but Transport Sessions are not supported in jTSS.
If you really need them you would have to implement them yourself.

I believe TrouSerS for C supports this feature.

I hope this helps a little bit,
Ronald
