Abstract
Secure transmission over an insecure channel can be achieved through the compression of data for efficiency followed by encrypting it for security. By reversing the operations, it is possible to improve secrecy. The lossless compression of encrypted sources can be achieved through Slepian-Wolf coding. The use of markov properties in the Slepian-Wolf decoder do not work well for grayscale images. This drawback can be rectified by Resolution Progressive Compression (RPC) scheme which compresses the encrypted image progressively in resolution such that the decoder can observe a low resolution version of image, study the local statistics based on it and use statistics to decode the next resolution level.
