Method and System for Secure Data Processing

摘要

Described herein are embodiments that relate to a method for use in data processing. An embodiment includes providing an arithmetic unit configured to perform any one in a set of operations. An embodiment includes providing a control register configured to hold control data. An embodiment includes providing in the set of operations, a control operation to provide process control, the control operation to operate on an operand that is coupled to the control data. A system for use in data processing is also disclosed having process registers and a control register. Further, a non-transitory computer-readable medium storing instruction code thereon for use in data processing is disclosed. When executed, the code causes a control operation forming part of a set of operations to operate on an operand that is coupled to control data held in a control register.

主权项

1. A device, comprising:
a processor; and a hardware component, wherein the processor is configured to verify execution of at least one task expressed by high-level instructions, and wherein a single high-level instruction, when executed, is configured to cause the processor to: directly access the hardware component to store an address where a signature value is stored; directly access the hardware component to modify the stored signature value to generate a verification value; and store the generated verification value at the address as an updated signature value.
