Abstract: A method of GPU virtualization comprises allocating each virtual machine (or operating system running on a VM) an identifier by the hypervisor and then this identifier is used to tag every transaction deriving from a GPU workload operating within a given VM context (i.e. every GPU transaction on the system bus which interconnects the CPU, GPU and other peripherals). Additionally, dedicated portions of a memory resource (which may be GPU registers or RAM) are provided for each VM and whilst each VM can only see their allocated portion of the memory, a microprocessor within the GPU can see all of the memory. Access control is achieved using root memory management units which are configured by the hypervisor and which map guest physical addresses to actual memory addresses based on the identifier associated with the transaction.

Abstract: The operation of a GPU is controlled based on one or more deadlines by which one or more GPU tasks must be completed and estimates of the time required to complete the execution of a first GPU task (which is currently being executed) and the time required to execute one or more other GPU tasks (which are not currently being executed). Based on a comparison between the deadline(s) and the estimates, the operating parameters of the GPU may be changed.

Abstract: Methods and devices are provided for use in detecting relay attacks between devices in a communications network. One method includes sending first data by a first device to a second device, and receiving, by the first device, a communication from the second device where the communication comprises second data generated at the second device and a time parameter related to the generation of the second data. The method also includes measuring a total transmission time at the first device between sending the first data and receiving the communication, and determining a further time parameter related to the generation of the second data based at least in part on the measured total transmission time. The method then further includes determining the presence of a relay attack between the first and second devices in dependence on a comparison of the time parameter and the further time parameter.

Abstract: A system and method for generating an authentication token which is used by an issuer associated with a integrated circuit card to authenticate a transaction. A personal card reader receives data, including an authentication cryptogram, from the integrated circuit card. The personal card reader uses the data received from the integrated circuit card to select one of at least two default bitmaps stored in a memory portion of the personal card reader. The personal card reader uses the selected default bitmap and the authentication cryptogram to build the authentication token.
