In this letter, we explore the emerging security threats of near-threshold computing (NTC). Researchers have shown that the delay sensitivity of a circuit to supply voltage variation tremendously increases, as the circuit's operating conditions shift from traditional super-threshold values to NTC values. As a result, NTC systems become extremely vulnerable to timing fault attacks, jeopardizing trustworthy computing. Inspired by the operation of a polymorphic virus, we propose a novel threat model for NTC, referred to as a focally induced fault attack (FIFA). FIFA employs a machine learning framework to ascertain the circuit vulnerabilities and generates targeted software modules to cause …

Power supply noise (PSN) is a growing concern in modern multiprocessor system-on-chips (MPSoCs). The advent of new architectures, such as the network-on-chip (NoC), the standard for on-chip communication in MPSoCs, has given rise to new challenges in maintaining reliable and energy-efficient operation. The growing NoC power footprint, increase in the transistor current, and high switching speed of the logic devices exacerbate the peak PSN in the NoC power delivery network (PDN). Hence, preserving power supply integrity in the NoC PDN is critical. In this paper, we propose IcoNoClast, a collection of a novel flow-control protocol (PAF) and an adaptive routing …
