Speculation Attack Against Intel's SGX

Another speculative-execution attack against Intel's SGX. At a high level, SGX is a new feature in modern Intel CPUs which allows computers to protect users' data even if the entire system falls under the attacker's control. While it was previously believed that SGX is resilient to speculative...
