VLSI intellectual property (IP) reuse based design methodology was adopted by the semiconductor industry in the early 1990's and how to protect design IPs from piracy and misuse has since been a challenging problem. 2017 marks the 20th anniversary of the IP protection development and working group was founded and the first series of IP watermarking papers were published. In this paper, we survey the...
To save resources for Internet of Things (IoT) devices, a proposed approach segments operands and corresponding basic arithmetic operations that can be carried out by approximate function units for almost all applications. The approach also increases the security of IoT devices by hiding information for IP watermarking, digital fingerprinting, and lightweight encryption.
Obfuscation has emerged as a promising approach to ensure supply chain security by countering the reverse engineering (RE) based attacks on integrated circuits that violate intellectual property rights of the circuit designer. However, current obfuscation methods either rely on secure memory to store the key or incur large design overhead with camouflaged gates. We propose a set of don't care based...
