Confidential Computing environments keep data encrypted in memory and elsewhere outside the central processing unit (CPU). Aren't Amazon's Graviton 2 processor

Confidential Computing environments keep data encrypted in memory and elsewhere outside the central processing unit (CPU).
Aren't Amazon's Graviton 2 processors specified to do this too?
- theevilsharpie 6y agoMy knowledge of Graviton is limited, but based on Amazon's description of Graviton 2's encryption capabilities, it seems more like an equivalent to AMD's Secure Memory Encryption (SME), rather than SEV.
- ENOTTY 6y agoIt's a lot more than just a SME equivalent. They've designed the management plane in a really clever way that makes it more similar to SGX/SEV than at first glance. I recommend watching this video https://www.youtube.com/watch?v=kN9XcFp5vUM https://www.youtube.com/watch?v=kN9XcFp5vUM
