Patent ID: 8434158

Claim:
A tampering detection system in a secured system, comprising: a security mesh network that comprises a plurality of security elements, each security element being made from a conductive metal wire located above a sensitive area of an integrated circuit; a random number generator that generates a plurality of random numbers; a security controller, coupled between the random number generator and the security mesh, the security controller randomizing the security mesh network by selecting a subset of the plurality of security elements according to at least one random number, forming a security array according to an array configuration, and generating a driving stimulus to drive the security array at at least one FORCE node; and a security monitor, coupled to the security mesh network and the security controller, the security monitor selecting at least one SENSE node, monitoring an output at the SENSE node according to a detection mode, and generating a flag signal indicating whether a tampering attempt is detected, the detection mode being associated with the driving stimulus.
