Abstract
An Integrated Circuit (IC) determines tampering of a communication channel between one or more components by determining, via a channel equalizer coupled to the communication channel, filter coefficients of the communication channel. The IC further compares, via a comparator, the filter coefficients to a tamper threshold and indicates tampering of the data channel when the tamper threshold is exceeded. The tamper threshold is determined by the channel equalizer based, in part, on initial filter coefficients.
