Abstract

In contradiction to one-dimensional mapping, higher-dimensional mapping may be conservative (volume preserving) as well as dissipative (volume contracting), invertible as well as non-invertible, depending on the parameter in the model. In this paper, we use two-dimensional chaotic maps, specifically Henon map [1], for compression as well as encryption. The Henon map is used to construct a private-key block cryptosystem.
