Researchers Design Chip that Identifies Defects, Monitors Performance

A team of researchers has designed a new solution to malicious circuitry in device chips. The team's chip contains an embedded module that monitors its own computations and flags defects before attackers can sabotage devices. 

The embedded module proves its own calculations are correct, and its external module validates the first module's proofs. Siddharth Garg, and assistant professor of electrical and computer engineering at Tandon, created a configuration that is an example of "verifiable computing," an approach that monitors a chip's performance and can identify trojans.
