Abstract:Cloud computing environments increasingly provision field-programmable gate arrays (FPGAs) for their programmability and hardware-level parallelism. While FPGAs are typically used by one tenant at a time, multitenant schemes supporting spatial sharing of cloud FPGA resources have been proposed in the literature. However, the spatial multitenancy of FPGAs opens up new attack surfaces. Investigating potential security threats to multitenant FPGAs is thus essential for better understanding and eventually mitigati… Show more
