Abstract
A method of obfuscating executable computer code to impede reverse-engineering, by interrupting the software's execution flow and replacing in-line code with calls to subroutines that do not represent logical program blocks. Embodiments of the present invention introduce decoy code to confuse attackers, and computed branching to relocated code so that actual program flow cannot be inferred from disassembled source representations.
