Abstract

In some embodiments, a computer-implemented method includes receiving, at a security agent of a host central processing unit (CPU), accelerator firmware from flash memory; determining, at the security agent, whether the accelerator firmware includes a critical accelerator firmware component or a non-critical accelerator firmware component; authenticating, at the security agent, the critical accelerator firmware component instantaneously upon a determination that the accelerator firmware is the critical accelerator firmware component, wherein authenticating the critical accelerator firmware component yields an authenticated critical accelerator firmware component; and providing the authenticated critical accelerator firmware component to an accelerator via a sideband bus for execution at the accelerator.
