What are the security differences between TPM1.2, TPM2.0, Intel PTT, and AMD fTPM?
As far as I am aware, to the OS, PTT, and fTPM are indistinguishable from TPM2.0. What I am curious about, are the physical security differences between the different TPM providers. A dedicated TPM2 module is susceptible to probing of the data lines to extract the encryption keys, so I wonder if PTT and fTPM are more secure in this respcet since, as far as I understand, they reside within the CPU. What other possible security vulnerabilities are there for these different TPM types?
