Logic encryption is a popular technique to safeguard an IC design from different security vulnerabilities. However, several recently proposed attacks can extract the secret keys of an encrypted design. In this paper, we propose a new logic encryption strategy, which integrates an additional key generation unit with the design. The key generation unit takes external keys and performs a permutation...
With the globalization of IC design flow, many fabless companies outsource the fabrication of their design to off-site foundries. As these foundries may not always be trusted, it results in security vulnerabilities and threats such as counterfeiting, IP piracy, reverse engineering, overbuilding and Hardware Trojans. Logic encryption has emerged to be a potential solution to secure the design against...
Diagnosis is extremely important to ramp up the yield during the integrated circuit manufacturing process. It reduces the time to market and product cost. High-volume diagnosis has become crucial for yield learning. The backbone of any diagnosis algorithm is the test set in use. Application of test sets for high-volume testing is typically done in test data compression environment to reduce the test...
