Duplication Based One-to-Many Coding for Trojan HW Detection
2010 IEEE 25th International Symposium on Defect and Fault Tolerance in VLSI Systems
A functional unit having multiple errors on its output may be considered as a computational channel, in which there is no restriction on the direction and the number of bit-flips. This model characterizes the distortion of the output caused by an active Trojan hardware. In this paper, we present a Concurrent Error Detection (CED) scheme that detects an active Trojan with high probability within a given time. The suggested CED scheme consists of a duplication-based one-to-many code that protectsdoi:10.1109/dft.2010.26 dblp:conf/dft/KerenLK10 fatcat:tgnqtd2vybcmbgth5bbqnm6xo4
