Categories of malicious hardware, the problem of foundry trust, and attacks facilitated by malicious inclusions are presented. This chapter also explains the problem of covert channels on FPGAs, with a formal definition of a covert channel in general and a description of the specific case of covert channels on FPGAs. Methods for detecting and mitigating these covert channels are also described.
