Research of Software Information Hiding Algorithm Based on Packing Technology

Abstract

This paper presents a software information hiding technique based on packing under Windows. The main function of the system includes identifying PE files, PE file packing, PE file code encryption, PE file information implantation, PE file information extraction, etc. The system uses the dynamic link library as a shell program, implants the end of the target PE file, implants the given information into the code segment, and encrypts the code segment with the information to be hidden by using shelling technology to complete the information hiding. The paper encrypts the information with the code segment, mixing the two. Even if adversary obtains this piece of data, it can’t distinguish between the effective information, effectively reduces the density of information, and increases the difficulty of information recognition, so as to achieve the purpose of information hiding.
