Disclosed herein are systems, computer-implemented methods, and computer-readable storage media for obfuscating data based on a discrete logarithm. A system practicing the method identifies a clear value in source code, replaces the clear value in the source code with a transformed value based on the clear value and a discrete logarithm, and updates portions of the source code that refer to the clear value such that interactions with the transformed value provide a same result as interactions with the clear value. This discrete logarithm approach can be implemented in three variations. The first variation obfuscates some or all of the clear values in loops. The second variation obfuscates data in a process. The third variation obfuscates data pointers, including tables and arrays. The third variation also preserves the ability to use pointer arithmetic.
