Abstract

An apparatus to facilitate enabling secure communication via attestation of multi-tenant configuration on accelerator devices is disclosed. The apparatus includes a processor to: verify a base bitstream of an accelerator device, the base bitstream published by a cloud service provider (CSP); verify partial reconfiguration (PR) boundary setups and PR isolation of an accelerator device, the PR boundary setups and PR isolation published by the CSP; generate PR bitstream to fit within at least one PR region of the PR boundary setups of the accelerator device; inspect accelerator device attestation received from a secure device manager (SDM) of the accelerator device; and responsive to successful inspection of the accelerator device attestation, provide the PR bitstream to the CSP for PR reconfiguration of the accelerator device.
