Abstract

In this paper, a new algorithm combined compression and image encryption is presented. The proposed algorithm can be used in the field of high-speed confidential data transmission where security is required. The compression is based on a hierarchical structure called SPIHT(Set Partitioning in Hierarchical Trees). This compression is followed by an encryption scheme PSCS (Parametric Switching Chaotic System). The performances of this technique were evaluated in terms of compression quality and data security. Simulation results have shown the effectiveness of this technique, and thereafter, it is ready for a hardware implementation.
