Code fusion information-hiding algorithm based on PE file function migration

Abstract PE (portable executable) file has the characteristics of diversity, uncertainty size, complexity structure, and singleness format, which make it easy to be a carrier information hiding, especially for that large hiding capacity. This paper proposes an information-hiding algorithm based on function migration, utilizes disassembly engine disassemble code section file, processes recognition, shifts whole codes system or user-defined functions last file. Then hides in original space. The hidden is combined with main coupled key program, further enhances concealment performance anti-attack capability system.
