Securing IP Cores for DSP Applications Using Structural Obfuscation and Chromosomal DNA Impression

This paper presents a novel hybrid methodology with structural obfuscation and encrypted chromosomal DNA impression to secure intellectual property (IP) cores of digital signal processing (DSP) applications. The proposed work offers security against altering register transfer level (RTL) description using multilevel as well IP piracy secret impression. In this approach, an invisible is covertly implanted into the structurally obfuscated DSP design robust encoding encryption multi-iteration Feistel cipher. Our more than recent facial biometric steganography-based hardware techniques, in terms stronger proof evidence tamper tolerance ability. results report following qualitative quantitative analysis based framework: (a) very low probability coincidence (Pc) (indicating strength evidence) for different range 7.59E-5 1.2E-1; (b) 5.62E+14 3.40E+38; (c) negligible cost overhead 0.00 % cores; (d) number gates obfuscated.
