  • Publication number: 20180101484
    Abstract: A computing device includes technologies for securing indirect addresses (e.g., pointers) that are used by a processor to perform memory access (e.g., read/write/execute) operations. The computing device encodes the indirect address using metadata and a cryptographic algorithm. The metadata may be stored in an unused portion of the indirect address.

  • Patent number: 9588771
    Abstract: In one embodiment, the present invention includes a method for directly communicating between an accelerator and an instruction sequencer coupled thereto, where the accelerator is a heterogeneous resource with respect to the instruction sequencer. An interface may be used to provide the communication between these resources. Via such a communication mechanism a user-level application may directly communicate with the accelerator without operating system support. Further, the instruction sequencer and the accelerator may perform operations in parallel. Other embodiments are described and claimed.

  • Publication number: 20170017791
    Abstract: Embodiments of an invention for a return address overflow buffer are disclosed. In one embodiment, a processor includes a stack pointer to store a reference to a first return address stored on a stack, an obscured address stack pointer to store a reference to an encrypted second return address stored in a memory, hardware to decrypt the encrypted second return address to generate a decrypted second return address, and a return address verification logic, responsive to receiving a return instruction, to compare the first return address to the decrypted second return address.

  • Patent number: 9519773
    Abstract: In an embodiment, the present invention includes a processor having a decode unit and an execution unit. The decode unit is to decode control transfer instructions and the execution unit is to execute control transfer instructions, the control transfer instructions including a call instruction and a return instruction. The processor is to operate in a first mode in which the processor is to raise a fault if a next instruction to be executed immediately after the return instruction is not the call instruction.

  • Publication number: 20160323297
    Abstract: Technologies are provided in embodiments for receiving policy information associated with at least one security exception, the security exception relating to execution of at least one program, determining an operation associated with the security exception based, at least in part, on the policy information, and causing the operation to be performed, based at least in part, on a determination that the at least one security exception occurred.

  • Publication number: 20130219399
    Abstract: In an embodiment, a method is provided. The method includes managing user-level threads on a first instruction sequencer in response to executing user-level instructions on a second instruction sequencer that is under control of an application level program. A first user-level thread is run on the second instruction sequencer and contains one or more user level instructions. A first user level instruction has at least 1) a field that makes reference to one or more instruction sequencers or 2) implicitly references with a pointer to code that specifically addresses one or more instruction sequencers when the code is executed.
