Abstract:
Due to the cost and complexity of current multicore
CPUs, chipmakers rely heavily on third-party IPs. A hostile IP
or hardware Trojan (HT) on the Network-on-Chip (NoC) can
degrade or leak packets. Several ways to identify HT in NoCs
have been presented, but they are not robust. In this work, we
propose the Blaming Hardware Trojan (BHT), which causes false
positive HTs by exploiting current security features to decrease
system performance. The proposed BHT attack can reduce
affected router performance by 36.39%, and overall performance
by 9.79%. The proposed countermeasure can recover it by losing
only 2.6% performance.
