Abstract
The present invention is directed to a method for verifying the integrity and authenticity of a printed circuit board, including associated components and packaging. The method is based on analyzing the power integrity of the power distribution network of the printed circuit board by measuring the S-parameter for the printed circuit board. Any tampering or counterfeiting can be determined by comparison of the S-parameter data or signature to a known authentic signature.
Claims9
A method for verifying whether a printed circuit board is authentic, comprising:
- characterizing a power distribution network of a printed circuit board to produce a signature based upon a reflection response parameter;
- and
- comparing the signature from said characterizing to a known signature based upon a reflection response parameter for a corresponding authentic printed circuit board to identify differences.
A method for verifying whether a printed circuit board is authentic, comprising:
- characterizing a power distribution network of a first printed circuit board to produce a first signature based upon a reflection response parameter;
- characterizing a power distribution network of a second printed circuit board to produce a second signature based upon a reflection response parameter;
- and
- determining a distance between the first signature and the second signature.
