Abstract
Side channel attacks against a computing device are prevented by combinations of scrambling data to be stored in memory and scrambling the memory addresses of the data using software routines to execute scrambling and descrambling functions. Encrypted versions of variables, data and lookup tables, commonly employed in cryptographic algorithms, are thus dispersed into pseudorandom locations. Data and cryptographic primitives that require data-dependent memory accesses are thus shielded from attacks that could reveal memory access patterns and compromise cryptographic keys.
