Processor attack detection method based on jump-related instructions
A newly filed patent (Publication Number: US20240037221A1) outlines an attack detection method for a processor. The method involves executing jump-related instructions in different privilege level modes, setting register fields to state parameters based on instruction execution, jumping to corresponding instructions, and determining the legality of instructions and parameters to decide on sending alert messages. The method includes handling interruptions, storing values in registers, and transitioning between privilege levels to enhance security measures.
Furthermore, the patent describes a processor designed to implement the attack detection method. The processor includes a register for a specific privilege level mode and an execution unit responsible for executing jump-related instructions, setting register fields, determining instruction legality, and sending alert messages based on evaluation results. The processor is equipped to handle interruptions, store and retrieve values in registers, and transition between privilege levels to ensure robust security protocols. The processor's functionality is tailored to efficiently detect and respond to potential attacks, enhancing the overall security posture of systems utilizing this technology.
