Recent trends in integrated circuits industry include decentralization of the production flow by involving different integration teams, third-party IP vendors and other untrusted entities. As a result, this is opening up a door to new types of attacks that may lead to devastating consequences, such as denial of service or data leakage. Therefore, the problem of ensuring hardware security has gained much attention in the last years, especially early in the design cycle, when an attacker may insert malicious circuitry at register transfer (RT) or gate level. Due to the increased complexity of modern devices, the research community is spending a lot of effort in developing more sophisticated detection methodologies and smarter attacks. However, the main problem is that they are validated on the existing benchmarks that do not reflect the real complexity. Trying to fill this gap, this paper proposes a set of RT-Level Hardware Trojan benchmarks injected in a RISC-based pipelined microprocessor core. To prove the viability, the impacts on area, power and frequency are presented and discussed. For any proposed Hardware Trojan, the functional description, the implementation details and the effects once activated are provided.
