Weakness in Intel chips lets researchers steal encrypted SSH keystrokes
In late 2011, Intel introduced a performance enhancement to its line of server processors that allowed network cards and other peripherals to connect directly to a CPU’s last-level cache, rather than following the standard (and significantly longer) path through the server’s main memory. By avoiding system memory, Intel’s DDIO—short for Data-Direct I/O—increased input/output bandwidth and […]
