N2 - In this article we propose the use of nonlinear exact chaotic system state reconstructors for the fast and efficient decoding of multiple discrete-time chaotic encrypted digital messages. Exact state reconstruction features a state estimation error which settles to zero in a finite number of steps. This makes the method specially suitable for chaotic encrypted transmission of digitized files over "noise-free" environments such as the Internet. The method was tested in an actual transmission involving the simultaneous decoding of digitized color images and text files.
