Multi-Tenant Cloud FPGAs: Side-Channel Security and Safety

FPGAs are increasingly being used in cloud systems, mainly due to their performance and energy advantages. Recent FPGAs have a relatively large amount of resources, which enables multi-tenancy and hence improves the utilization and economic value for both the cloud providers and customers. However, the ability to co-locate designs from different tenants requires efficient safeguards and support. In this talk, I will explore security and safety issues related to multi-tenant cloud FPGA. Specifically, I will describe recent work on remote physical side-channel attacks and power safety issues, and how to mitigate them for next-generation cloud infrastructure.
