Abstract

Embodiments of the invention provide method and system for defense against ROP attacks. The method comprises: identifying a substitutable instruction pair in a binary file, which includes a first instruction for pushing a first group of registers into a stack memory, and a second instruction for popping the first group of registers off the stack memory, generating an equivalent instruction pair for the substitutable instruction pair, which includes a first equivalent instruction for pushing a second group of registers onto the stack memory, and a second equivalent instruction for popping the second group of registers off the stack memory, wherein the second group of registers includes the first group of registers and at least one additional register which is not used by the substitutable instruction pair, and overwriting the first instruction and the second instruction with the first equivalent instruction and the second equivalent instruction respectively.

Description

technical field [0001] The present invention relates generally to Return Oriented Programming (ROP) mitigation strategies, and more specifically to defense against Autoencoder / Advanced Reduced Instruction Set Computing (RISC) machines (Advanced Reduced Instruction Set Computing (RISC) A method and system for ROP-based attacks in mobile computer systems running on Computing Machine (ARM) architecture. Background technique [0002] ROP is an advanced software development technique that enables attackers to achieve malicious goals without injecting code. ROP-based attack techniques are widely used in software and system development to evade modern security defense techniques such as non-executable storage and code signing. ROP-based attack techniques can be applied to various computer systems, for example, desktop computer systems operating on the X86 platform and mobile computer systems operating on the ARM architecture, for example, the Apple mobile phone operating system (i...
