Secure FFT IP using C way Partitioning based Obfuscation and Fingerprint

Abstract

This paper presents a secure intellectual property (IP) core design of N-point decimation in time-fast Fourier transform (DIT-FFT) using C-way partitioning-based structural register transfer level (RTL) obfuscation and coded fingerprint biometric distribution using high level synthesis (HLS). The proposed methodology firstly generates the obfuscated design of FFT using RTL obfuscation, followed by scheduling each resulting partition, capable of hindering the RTL alteration. Next, the fingerprint biometric template is generated based on the minutiae feature points. Thereafter, IP vendor fingerprint signature is selected based on the coded distribution for embedding into each partition, capable of detecting pirated IP. Thus, by embedding the fingerprint security constraints into an obfuscated design, the proposed methodology enables robust security of FFT. IEEE
