Hello,
Supposing I was using a TPM that is connected to its host device via the SPI bus, would it be possible to encrypt all communication over that bus. I recently read the TPMgeany papers, linked here: https://github.com/nccgroup/TPMGenie in which a man-in-the-middle attack could be used to spoof packets to and from the TPM.
I was curious if The ESAPI, SAPI or something else could be used to encrypt communication over the SPI bus to mitigate these vulnerabilities.

Thank you for your time,
James Gallagher
