Classifying Computations on Multi-Tenant FPGAs
Hosted in Virtual Platform
Hardware Security: Primitives, Architecture, Design & Test
DescriptionModern data centers leverage large FPGAs to provide low latency, high throughput, and low energy computation. FPGA multi-tenancy is an attractive option to maximize utilization, yet it opens the door to unique security threats. In this work, we develop a remote classification pipeline that targets the confidentiality of multi-tenant cloud FPGA environments. We utilize a voltage fluctuation sensor that measures subtle changes in the power distribution network caused by co-located computations. The sensor measurements are given to a classification pipeline that is able to deduce information about co-located applications including the type of computation and its implementation.
