Eliminating infamous security threats


Speculative side-channel attacks exploit a fundamental functionality in

microprocessors to expose security vulnerabilities. The first such security
threats, Meltdown and Spectre, were announced last year, but many more have been discovered since. Previous security solutions have been limited and often incurred a high performance penalty.
Now, researchers from Uppsala University, NTNU, and University of Murcia have come up with a more appealing solution, which will be presented at the prestigious International Symposium on Computer Architecture (ISCA) at the end of June.
"Our solution reduces the performance and energy costs, and increases the security of the computer system, when compared to previous solutions," says Christos Sakalis, Ph.D. student at Uppsala University.
