The disclosed embodiments provide security extensions for memory (e.g., non-volatile memory) by means of address and data scrambling and differential data storage to minimize exposure to side channel attacks and obfuscate the stored data. The scrambling function maximizes reverse engineering costs when recovering sequences of secret keys.
