Malware Guard Extension: abusing Intel SGX to conceal cache attacks
Cybersecurity, 2020 In modern computer systems, user processes are isolated from each other by the operating system and the hardware. Additionally, in a cloud scenario it is crucial that the hypervisor isolates tenants from other tenants that are co-located on the same ...
