Abstract
A mesh grid protection system is provided. The protection system includes a plurality of grid lines forming a mesh grid proximate to operational logic. The protection system also includes tamper-detection logic coupled to the plurality of grid lines and configured to toggle a polarity of a signal on at least one grid line at each clock cycle and to detect attempts to access the operational logic by comparing a reference signal driving a first end of a grid line to a signal at the opposite end of the grid line.
