Research and Implementation of Dynamically Packing Technology for PE Files
Pang Li-hui · Jisuanji gongcheng · 2008
It is an effective method to protect software by packing Portable Executable(PE) files. But the technology which is commonly used by most packing software is a statically packing technology, and it exists a shortage that all the PE files packed by the same packing software have partly uniform code, thus increases the possibility of the packed software being decrypted, which can not fully satisfy the requirement to protect PE files. Based on the analysis of the PE file format and loading mechanism, this paper proposes the idea of dynamically packing for PE files, designs and implements a prototype of dynamically packing for PE files. The experimental results show dynamically packing technology can be used to improve the protection capability of PE files.
