    摘要： An apparatus to facilitate enabling stateless accelerator designs shared across mutually-distrustful tenants is disclosed. The apparatus includes a fully-homomorphic encryption (FHE)-capable circuitry to establish a secure session with a trusted environment executing on a host device communicably coupled to the apparatus; generate, as part of establishing the secure session, per-tenant FHE keys for each tenant utilizing the FHE-capable circuitry, the per-tenant FHE keys utilized to encrypt tenant data provided to an FHE-capable compute kernel of the FHE-capable circuitry; process tenant data that is in an FHE-encrypted format encrypted with a per-tenant FHE key of the per-tenant FHE keys; and store the tenant data that is in the FHE-encrypted format encrypted with the per-tenant FHE key of the per-tenant FHE keys.

    摘要： An apparatus and method for securely suspending and resuming the state of a processor. For example, one embodiment of a method comprises: generating a data structure including at least the monotonic counter value; generating a message authentication code (MAC) over the data structure using a first key; securely providing the data structure and the MAC to a module executed on the processor; the module verifying the MAC, comparing the monotonic counter value with a counter value stored during a previous suspend operation and, if the counter values match, then loading processor state required for the resume operation to complete. Another embodiment of a method comprises: generating a first key by a processor; securely sharing the first key with an off-processor component; and using the first key to generate a pairing ID usable to identify a pairing between the processor and the off-processor component.

    摘要： Embodiments for dynamically mitigating speculation vulnerabilities are disclosed. In an embodiment, an apparatus includes speculation vulnerability detection hardware and execution hardware. The speculation vulnerability detection hardware is to detect vulnerability to a speculative execution attack and, in connection with a detection of vulnerability to a speculative execution attack, to provide an indication that data from a first operation is tainted. The execution hardware is to perform a second operation using the data if the second operation is to be performed non-speculatively and to prevent performance of the second operation if the second operation is to be performed speculatively and the data is tainted.
