This talk will introduce the audience to two new x86 ISA features developed by AMD which will provide new security enhancements by leveraging integrated memory encryption hardware. These features provide the ability to selectively encrypt some or all of system memory as well as the ability to run encrypted virtual machines, isolated from the hypervisor. The talk will cover technical details related to these features, including the ISA changes, security benefits, key management framework, and practical enablement. The main objective of the talk is to educate the audience on the design and use of these features which are the first general-purpose memory encryption features to be integrated into the x86 architecture.
