Abstract: A method of authenticating shared peripheral component interconnect express devices of a switched fabric includes associating at least one requester identifier with a physical function of a device on the switched fabric and instantiating a virtual function of the device based on the physical function. The virtual function includes the associated at least one requester identifier. The method further includes accepting memory-mapped input/output traffic through the virtual function only from a requester having a corresponding requester identifier matching an associated requester identifier of the virtual function. The method may also include allowing a write operation of the virtual function or the physical function only to an address residing within an allowable address range associated with the device.
