Embodiment Construction

[0035] The present invention selects the current research hotspot in the Android platform—the software protection method based on ARM instruction virtualization as the research object to evaluate the energy consumption of this type of protection method in the software protection process. The principle of the ARM instruction virtualization protection method is basically the same as that of the virtual machine protection method on the traditional computer. The ARM instruction virtualization protection mainly protects the local layer code of the APP. Instructions) are converted into a self-defined virtual instruction. When the program is executed, these virtual instructions are interpreted and executed one by one by a virtual interpreter, so as to realize the original function of the instruction to be protected. The advantage of ARM instruction virtualization protection is that it greatly increases the cost of reverse analysis for attackers and can effectively protect software. C...

Abstract

The invention discloses an ARM instruction virtualization-based software protection energy consumption evaluation method. First, a proper and precise scheme for measuring smart phone electric quantity is designed and a testing platform is established; a comparative research is made to before and after conditions of a program using the ARM instruction virtualization protection method, and a rational testing program is designed; the testing program is operated on the smart phone and electric quantity changes of the phone during the operation of the test program is measured and recorded; data acquired by measurement is analyzed, and effects of the ARM instruction virtualization protection method to energy consumption is researched and concluded; a linear regression model is utilized to generate a linear regression equation; and energy consumption due to the use of the ARM instruction virtualization protection method can be predicted and evaluated. By the use of the method, a software developer can easily learn the effects of the employed software protection method to the energy consumption, so a great balance can be maintained between software protection strength and final energy consumption.

Description

technical field [0001] The invention belongs to the technical field of smart phone energy consumption evaluation, and in particular relates to an evaluation method for software protection energy consumption based on ARM instruction virtualization. Background technique [0002] The smartphone market has been growing at a phenomenal rate, and as people rely on their smartphones for functionality and entertainment, battery life is the biggest concern. However, many aspects of smartphones have improved dramatically, but battery life is still an important factor affecting the experience of millions of users. How to improve smartphone battery life? On the one hand, it is to study the replacement of batteries with larger capacity, which is difficult to make a breakthrough in the current technology; on the other hand, it is the optimization of energy consumption, which is the focus of current researchers. [0003] However, while the development of smart phones has brought huge ben...
