Abstract :
Breaking with the traditional modular architecture in which compression and cryptography are carried out separately, we propose an analysis-by-synthesis approach that exploits the properties of source codes to ensure a prescribed level of protection with manageable computational complexity. To illustrate the power of this methodology, we show that carefully inducing catastrophic errors in Huffman coded streams is very effective towards confusing a passive attacker.
