[Legacy Report] MAGIC: Malicious Aging in Circuits/Cores

#VLSI #Design #IC #Reliability #NBTI

The circuitry comprising an IC degrades over its lifetime, ultimately resulting in IC failure. While IC designers put a tremendous effort on reducing aging effects and enhancing the reliability of electronic chips, adversaries may aim at accelerating the wearout of these chips. In practice, a malicious adversary may accelerate the aging process of an IC and thus shorten the devices life span. This talk explores the security vulnerability of modern microprocessors against aging attacks and presents a hardware attack (called MAGIC) that maliciously accelerates NBTI aging effects in processor cores. By analyzing the structural information of a processor, a sequence of assembly instructions that accelerate the aging process is developed and a program consisting of these instructions is crafted. By executing this application, the core is maliciously aged and the chip fails sooner than expected.
