Dedicated Security Chips in the Age of Secure Enclaves

Kari Kostiainen, Aritra Dhar, Srdjan Capkun

Abstract: Secure enclave architectures have become prevalent in modern CPUs. Enclaves provide a flexible way to implement various hardware-assisted security services. But special-purpose security chips can still have advantages. Interestingly, dedicated security chips can also assist enclaves and improve their security.
