Abstract
Intellectual Property (IP) illegal copying is a major threat in today's integrated circuits industry which is massively based on a design-and-reuse paradigm. In order to fight this threat, a designer must track how many times an IP has been instantiated. Moreover, illegal copies of an IP must be unusable. We propose a hardware/software scheme which allows a designer to remotely activate an IP with minimal area overhead. The software modifies the IP efficiently and can handle very large netlists. Unique identification of hardware instances is achieved by integrating a TERO-PUF along with a lightweight key reconciliation module. A cryptographic core guarantees security and triggers a logic locking/masking module which makes the IP unusable unless the correct encrypted activation word is applied.
