TLDR
An algorithm for embedding compression in the Baptista-type chaotic cryptosystem is proposed and it is shown that the compression performance on standard test files is satisfactory while the security is not compromised.Abstract:
An algorithm for embedding compression in the Baptista-type chaotic cryptosystem is proposed. The lookup table used for encryption is determined adaptively by the probability of occurrence of plaintext symbols. As a result, more probable symbols will have a higher chance to be visited by the chaotic search trajectory. The required number of iterations is small and can be represented by a short code. The compression capability is thus achieved. Simulation results show that the compression performance on standard test files is satisfactory while the security is not compromised. Our scheme also guarantees that the ciphertext is not longer than the plaintext.read more

Simultaneous Arithmetic Coding and Encryption Using Chaotic Maps
TL;DR: A simultaneous compression and encryption scheme is proposed in which the chaotic map model for arithmetic coding is determined by a secret key and keeps changing, and the compressed sequence is masked by a pseudorandom keystream generated by another chaotic map.

TL;DR: This research examines the limitations of selective encryption using cryptanalysis, and proposes another approach that turns entropy coders into encryption ciphers using multiple statistical models that can be applied to most modern compressed audio/video such as MPEG audio, MPEG video, and JPEG/JPEG2000 images.
