Microprocessor Privilege Escalation Attack Simulation Method

Abstract

The invention provides a CPU privilege escalation attack simulation method. The method comprises the following steps of a. simulating original design data of a CPU so as to obtain an attacked target trigger circuit node; b. designing and realizing an attack circuit at the target trigger circuit node; c. verifying correctness of a function of the attack circuit through simulation or field programmable gate array (FPGA); and d. simulating privilege escalation attack by using the attack circuit. The effect of privilege escalation attack is simulated by embedding the attack circuit in the CPU. Compared with software simulation, hardware simulation is faster.

Description

technical field [0001] The invention belongs to the field of integrated circuit security, and in particular relates to a method for simulating a microprocessor authority elevation attack. Background technique [0002] Integrated Circuit (IC, Integrated Circuit) is the core of modern information equipment, and its security is increasingly concerned by people. The security of IC itself determines whether the information processed by it is safe or not. Traditional integrated circuit security attack methods mainly include side channel attack (SCA, Side Channel Attack), fault injection attack, intrusive attack and so on. Among them, the side channel attack mainly obtains the encryption key by detecting and analyzing the side channel signal of the integrated circuit; the fault injection attack bypasses the encryption key by artificially injecting faults into the chip, such as adding burrs to the power signal and irradiating the sensitive points of the chip with laser light. The s...
