Joint compression and data protection
2009 47th Annual Allerton Conference on Communication, Control …, 2009•ieeexplore.ieee.org
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.
