Abstract: An anti-counterfeiting circuit that is incorporated into an authentic integrated circuit (IC) design, which induces a random failure in a counterfeited IC when the counterfeit IC is manufactured from a reverse-engineered authentic IC. The anti-counterfeiting circuit uses two signals of differing frequencies, which activate a disrupt signal when the two signals meet a predetermined failure criteria, for example, equivalent rising edges. The disrupt signal causes a signal gate or similar element within the counterfeited IC to fail, disrupt, or in some way change a designed behavior of the IC. The disrupt signal may be reset so that the failure will occur again when predetermined failure criteria are met. The authentic IC functions according to design because at least one of the elements in the anti-counterfeit circuit is a camouflage circuit, thus, in an authentic IC the anti-counterfeit circuit is not operatively coupled.

Abstract: A verification system disclosed herein uses the unique signatures of an IC to perform authentication of the IC after the IC is shipped to a customer. The verification system records the fingerprint and associated IC identifier with the fingerprint into a data structure. The data structure is supplied to the customer for use in the customer's own security systems. When an IC interfaces with the customer's system, the verification system requests the IC's identifier and selects a data structure corresponding to that IC identifier. The verification system then performs a test on the IC (e.g. remotely operates the IC at 1V), records the resulting data and compares the test results with the corresponding data in the data structure. If a predetermined condition is satisfied then the IC is verified to be authentic. If not, the verification system responds, for example, by flagging the customer's security system.
