Claim 0:
1. A system for providing a secure collaboration between one or more PCIe accelerators and an enclave defined within memory of a host computing device, the system comprising:
a PCIe accelerator apparatus including:
the one or more PCIe accelerators;
a microcontroller configured to provide a cryptographic hardware identity to the PCIe accelerator apparatus, wherein the PCIe accelerator apparatus is configured to use the cryptographic hardware identity to negotiate a cryptographic session between the PCIe accelerator apparatus and the enclave; and
a cryptographic engine separate from the one or more PCIe accelerators and arranged in a PCIe path of the one or more PCIe accelerators to provide encryption and decryption operations between the one or more PCIe accelerators and the enclave during the cryptographic session.
