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); generate a partial reconfiguration (PR) bitstream based on the base bitstream, the PR bitstream to fit within at least one PR region of 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.

Claims (33)

1. An apparatus comprising:

a processor to:

verify a base bitstream of an accelerator device, the base bitstream published by a cloud service provider (CSP);

generate a partial reconfiguration (PR) bitstream based on the base bitstream, the PR bitstream to fit within at least one PR region of 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.

2. The apparatus of claim 1 , wherein the SDM comprises a configuration manager and security enclave for the accelerator device.

3. The apparatus of claim 1 , wherein a circuit design tool is utilized to inspect and verify the base bitstream, the PR boundary setups, and PR isolation, wherein the PR boundary setups and the PR isolation published by the CSP.

4. The apparatus of claim 3 , wherein the circuit design tool is utilized to generate the PR bitstream.

5. The apparatus of claim 1 , wherein a trusted agent of the CSP provides the accelerator device attestation.

6. The apparatus of claim 5 , wherein the SDM provides the accelerator device attestation to the trusted agent.

7. The apparatus of claim 1 , wherein the accelerator device attestation comprises an immutable accelerator device identifier (ID), a base bitstream ID, and a hash of a PR mask.

8. The apparatus of claim 1 , wherein the accelerator device comprises at least one of a graphic processing unit (GPU), a central processing unit (CPU), or a programmable integrated circuit (IC).

9. The apparatus of claim 8 , wherein the programmable IC comprises at least one of a field programmable gate array (FPGA), a programmable array logic (PAL), a programmable logic array (PLA), a field programmable logic array (FPLA), an electrically programmable logic device (EPLD), an electrically erasable programmable logic device (EEPLD), a logic cell array (LCA), or a complex programmable logic device (CPLD).

10. A method comprising:

verifying, by one or more processors, a base bitstream of an accelerator device, the base bitstream published by a cloud service provider (CSP);

generating a partial reconfiguration (PR) bitstream based on the base bitstream, the PR bitstream to fit within at least one PR region of PR boundary setups of the accelerator device;

inspecting accelerator device attestation received from a secure device manager (SDM) of the accelerator device; and

responsive to successful inspection of the accelerator device attestation, providing the PR bitstream to the CSP for PR reconfiguration of the accelerator device.

11. The method of claim 10 , wherein a circuit design tool is utilized to inspect and verify the base bitstream, the PR boundary setups, and PR isolation, wherein the PR boundary setups and the PR isolation published by the CSP.

12. The method of claim 11 , wherein the circuit design tool is utilized to generate the PR bitstream.

13. The method of claim 10 , wherein a trusted agent of the CSP provides the accelerator device attestation, and wherein the SDM provides the accelerator device attestation to the trusted agent.

14. The method of claim 10 , wherein the accelerator device attestation comprises an immutable accelerator device identifier (ID), a base bitstream ID, and a hash of a PR mask.

15. The method of claim 10 , wherein the accelerator device comprises at least one of a graphic processing unit (GPU), a central processing unit (CPU), or a programmable integrated circuit (IC), and wherein the programmable IC comprises at least one of a field programmable gate array (FPGA), a programmable array logic (PAL), a programmable logic array (PLA), a field programmable logic array (FPLA), an electrically programmable logic device (EPLD), an electrically erasable programmable logic device (EEPLD), a logic cell array (LCA), or a complex programmable logic device (CPLD).

16. A non-transitory machine readable storage medium comprising instructions that, when executed, cause at least one processor to at least:

verify, by the at least one processor, a base bitstream of an accelerator device, the base bitstream published by a cloud service provider (CSP);

generate a partial reconfiguration (PR) bitstream based on the base bitstream, the PR bitstream to fit within at least one PR region of 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.

17. The non-transitory machine readable storage medium of claim 16 , wherein a circuit design tool is utilized to inspect and verify the base bitstream, the PR boundary setups, and PR isolation, wherein the PR boundary setups and the PR isolation published by the CSP.

18. The non-transitory machine readable storage medium of claim 17 , wherein the circuit design tool is utilized to generate the PR bitstream.

19. The non-transitory machine readable storage medium of claim 16 , wherein a trusted agent of the CSP provides the accelerator device attestation, and wherein the SDM provides the accelerator device attestation to the trusted agent.

20. The non-transitory machine readable storage medium of claim 16 , wherein the accelerator device attestation comprises an immutable accelerator device identifier (ID), a base bitstream ID, and a hash of a PR mask.
