TLDR
Simulations were carried out on a conventional iterative turbo decoder and the results point out that the Trojan affects the performance of the decoder at SNRs greater than -2 dB.Abstract:
In complex systems like 'Internet of Things' and 'Cyber Physical Systems', reliable communication is made possible by the use of error control codes like turbo codes. Such systems are vulnerable to attack by Trojans during the design or fabrication phases of IC manufacturing. This leads to a severe performance degradation of the entire system. This paper aims at analyzing the effect of a sign-bit-flipping Trojan on a turbo coded communication system. Simulations were carried out on a conventional iterative turbo decoder and the results point out that the Trojan affects the performance of the decoder at SNRs greater than -2 dB. This performance degradation is seen even with minimal activation of the Trojan and a finite error persists even at very high SNRs.read more

Boosting the Bounds of Symbolic QED for Effective Pre-Silicon Verification of Processor Cores
TL;DR: In this paper, the authors leverage Symbolic Quick Error Detection (Symbolic QED or SQED), a recent bug detection and localization technique using Bounded Model Checking (BMC), and Symbolic starting states, to present a method that effectively detects both "difficult" logic bugs and hardware Trojans, even with long activation sequences where traditional BMC techniques fail.
