Intellectual property metering(22)

Abstract. We have developed the first hardware and software (intellectual property) metering scheme that enables reliable low overhead proofs for the number of manufactured parts and copied programs. The key idea is to make each design slightly different d

8 Conclusion

We have developed the first hardware and software (intellectual property) usage metering scheme. The scheme enables design companies to securely control licensing rights for their IP. The utilizes a small percentage of a design implemented using configurable tech-nology to embed a unique ID to each manufactured design instance. This scheme is gener-alized in a number of ways and applied to both hardware and software metering.

We also presented mathematical analysis for detection accuracy of the proposed scheme. We demonstrated the ability of the scheme to implement very high number of chips with different ID. The main result of the paper is that we established generic connec-tion between the scheme and synthesis and compilation tasks.
