In complex FPGA designs, implementations of algorithms and protocols from third-party sources are common. However, the monolithic nature of FPGAs means that all sub-circuits share common on-chip infrastructure, such as routing resources. This presents an attack vector for all FPGAs that contain designs from multiple vendors, especially for FPGAs used in multi-tenant cloud environments, or integrated into multi-core processors. In this article,...
