AMD’s Epyc server encryption is the latest security system to fall
It’s a good thing AMD had the sense not to rub Intel’s nose in the Meltdown/Spectre vulnerability, because it would be getting it right back for this one: Researchers from the Fraunhofer Institute for Applied and Integrated Safety in Germany have published a paper detailing how to compromise a virtual machine encrypted by AMD's Secure Encrypted Virtualization (SEV).
The news is a bit of a downer for AMD, since it just added Cisco to its list of customers for the Epyc processor. Cisco announced today plans to use Epyc in its density-optimized Cisco UCS C4200 Series Rack Server Chassis and the Cisco UCS C125 M5 Rack Server Node.
