A mesh grid protection system is provided. The system includes grid lines forming a mesh grid proximate to operational logic and assertion logic configured to transmit a first set of signals on a first set of grid lines. The system also includes transformation logic coupled to the grid lines and configured to receive the first set of signals and transform the first set of signals to generate a second set of signals and transmit the second set of signals on a second set of grid lines. The system further includes verification logic coupled to the transformation logic and configured to compare the second set of signals to an expected set of signals.
