SGX is a very interesting development. I agree with Johanna Rutkowska that "SGX might profoundly change the architecture of the future operating systems". Enhanced Privacy IDs are particularly interesting, since it will allow you to anonymously or pseudonymously authenticate a particular CPU: http://csrc.nist.gov/groups/ST/PEC2011/presentations2011/brickell.pdf http://csrc.nist.gov/groups/ST/PEC2011/presentations2011/bri... It's also very powerful to be able to attest secure enclaves with a root of trust within the CPU, rather than a TPM. It removes TPMs and the LPC bus as an attestation attack vector.
