Handling symmetrical IP core protection and IP protection (IPP) of Trojan-secured designs in HLS using physical biometrics

Abstract

The chapter describes the applications of biometric-based hardware security methodologies to provide symmetric protection of ownership rights for intellectual property (IP) buyer and seller. Additionally, it also presents the application of facial biometric-based hardware security for protecting Trojan-secured DSP designs against IP piracy (Chaurasia and Sengupta, 2022a, 2022b). To provide symmetric security for IP buyer and seller, first, the fingerprint biometric of IP buyer in the form of secret hardware security constraints is embedded into the digital signal processing (DSP) design during high-level synthesis (HLS). This embedded fingerprint signature IP buyer safeguards his/her rights against an adversary or an untrustworthy IP seller. Subsequently, post obtaining the IP buyer fingerprint embedded design, the facial biometric of IP seller is inserted into the design. Thus, the embedded security constraints (digital evidence) corresponding to fingerprint biometric and facial biometric signature of IP buyer and seller, respectively, enables the symmetric protection of their ownership rights. Additionally, in case of piracy, the embedded facial biometric signature also enables the robust and seamless detective control against pirated versions. Further, for protecting the Trojan-secured designs against IP piracy, first the Trojan-secured scheduled design is generated. Subsequently, the facial security constraints are inserted into the Trojan-secured design using HLS. These embedded facial security constraints enable the piracy detection control for Trojan-secured DSP designs as well. Thus, isolating pirated versions before integrating into system on chip (SoC) systems.The organization of the chapter is as follows: Section 5.1 discusses about the introduction of the chapter; Section 5.2 presents the discussion on contemporary approaches for symmetrical IP core protection; Section 5.3 explains the process of HLS-based symmetrical IP core protection using IP seller facial biometric and IP buyer fingerprint biometric; Section 5.4 shows the protection of IP seller right's against the false claim of IP ownership; Section 5.5 shows the protection of IP buyer right's using fingerprint biometric signature; Section 5.6 explains the piracy detection process; Section 5.7 presents the process of employing facial biometric for protecting Trojan-secured IP cores against piracy; Section 5.8 discusses and analyses the security and design cost of symmetrical IP core protection technique and for, protecting Trojan-secured designs against piracy; Section 5.9 concludes the chapter.
