Digital-to-Analog Hardware Trojan Attacks

We propose a Hardware Trojan (HT) attack for analog circuits with its key characteristic being that it cannot be prevented or detected in the domain. The HT works context of Systems-on-Chip (SoCs) comprising both digital and Intellectual Property (IP) blocks. attacker could either SoC integrator foundry. More specifically, trigger is placed inside dense IP block where can effectively hidden, whereas payload form pattern transported via test bus generated within bus, reaching Design-for-Test (DfT) programmability interface victim bus. unexpectedly activates DfT sets into some possibly partial undocumented mode changes nominal programmability. designed to result performance degradation complete malfunction, i.e., denial service. demonstrate this scenario on two IPs, namely low-dropout (LDO) regulator using simulation an RF receiver hardware measurements.
