In pursuit of this balance, we focused on the chain-generated noise masking technique, a security method using compressed sensing, which was proposed in prior research. In this paper, we discuss the power consumption of the chain-generated noise masking system from the perspective of circuit dynamic range and resolution, with an eye toward its practical implementation. The results of the security strength evaluation through simulations revealed that, with a compression ratio (CR) of 4, setting the watermark duration to 100????Vrms and the pseudo-noise duration to at least 250????Vrms provides sufficient resistance to attacks. Furthermore, it was confirmed through simulation that no additional resolution or dynamic range, which are closely related to power consumption of the device, is required due to the insertion of the watermark or noise.}, title = {圧縮センシングと連鎖生成雑音マスキングを活用したセキュリティシステムにおける設計手法の検証}, year = {2024} }
