Integrating multi-key-based structural obfuscation and low-level watermarking for double line of defence of DSP hardware accelerators

Abstract

The chapter describes a double line of defence mechanism for securing hardware accelerators using key-based structural obfuscation (SO) and physical-level watermarking. The presented approach discussed in this chapter is capable of securing against combined threat models of reverse engineering (leading to Trojan insertion) and intellectual property (IP) piracy as preventive and detective control. © The Institution of Engineering and Technology 2021.
