University of Virginia School of Engineering and Applied Science In 2018, industry and academic researchers revealed a potentially devastating hardware flaw that made computers and other devices worldwide vulnerable to attack. Researchers named the vulnerability Spectre because the flaw was built into modern computer processors that get their speed from a technique called “speculative execution,” in which the processor predicts instructions it might end up executing and preps by following the predicted path to pull the instructions from memory. A Spectre attack tricks the processor into e...

"Unhackable" MORPHEUS Chip Passes Its First Public Test, DARPA's FETT Bug Bounty, Unhacked Calling something "unhackable" doesn't usually end well, but the University of Michigan's MORPHEUS chip may prove to be just that. an hour ago • Security The University of Michigan's MORPHEUS chip, the testbed for a new approach to creating a computing device its creators claim is "unhackable," has completed its first real world test: passing a DARPA bug bounty challenge unscathed. Publicly unveiled two years ago, MORPHEUS is an implementation of a security approach combining encryption with what i...

 E-Mail Contemporary robots can move quickly. "The motors are fast, and they're powerful," says Sabrina Neuman. Yet in complex situations, like interactions with people, robots often don't move quickly. "The hang up is what's going on in the robot's head," she adds. Perceiving stimuli and calculating a response takes a "boatload of computation," which limits reaction time, says Neuman, who recently graduated with a PhD from the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL). Neuman has found a way to fight this mismatch between a robot's "mind" and body. The method, cal...

Designing customized “brains” for robots January 21, 2021MIT A new system devises hardware architectures to hasten robots’ response time.
