Implementing security by design.
In January 2018, Meltdown and Spectre were independently disclosed by multiple security researchers, including senior Rambus technology advisor Paul Kocher and senior Rambus security engineer Mike Hamburg. The two security flaws exploit critical vulnerabilities across a wide range of modern processors, including Intel, ARM and AMD. Notably, however, existing RISC-V processors remain unaffected by both Meltdown and Spectre.
Although Meltdown and Spectre are certainly not the first high-profile semiconductor security flaws to gain widespread attention, they do represent a new class of vulnerabilities related to out-of-order and speculative execution. To read more, click here.
