The ongoing globalization and specialization of the integrated circuit (IC) supply chain has led semiconductor companies to share their valuable intellectual property (IP) assets with numerous parties for means of manufacturing, testing, etc. As a consequence, sensitive IPs and ICs are being exposed to untrusted parties, resulting in serious piracy threats such as counterfeiting or reverse engineering. In this thesis we develop methods to secure analog and mixed signal IPs/ICs from piracy threats within the supply chain.
We demonstrate that establishing security and trust for analog and mixed signal IPs and ICs, while still in its infancy, is feasible. The presented techniques have the potential to protect analog and mixed-signal circuits against a large subset of all the possible risk scenarios while inflicting low overheads in terms of area, power and performance. The changes carried out in the ICs' analog sections are subtle, a key requirement for the adoption of our techniques by analog designers.
