A Chaos-Based Joint Compression and Encryption Scheme for Streaming data

An approach for improving the compression performance of chaos-based joint compression and encryption schemes is proposed. Instead of building the whole lookup tables before encryption, we dynamically develop the bi-gram lookup tables during the encryption steps. This dynamically construction model can solve the problem of huge overheads of LUTs and further enhance the performances. Moreover, unlike the previous related works, which are all static, we also propose a streaming scheme in addition to a static approach. Simulation results show that that the proposed modification leads to a better compression performance while the security is not compromised.
