Chaotic cryptology


  • Dedicated to Prof. Dr. Heinz Bethge on the occasion of his 75th birthday


A method to transfer secret information using chaotic dynamical systems is proposed. It is based on modulating a chaotic system with the message such that its time evolution contains the hidden information. Decryption of the cipher is achieved by chaos control. Operation of the scheme is demonstrated by en- and decoding a short german text.
