Abstract This paper proposes a software implementation of a symmetric encryption algorithm based on a mixture of the original plaintext with one of the state variables of Henon discrete chaotic system. The Visual C++ 6.0 environment was used for developing a software package. References [1] Mark E. Bianco, Dana A.
