Abstract :
A secure communication scheme based on symbolic dynamics is proposed. With a binary sequence extracted from a chaotic map the message to be transmitted is encrypted by employing the chaotic masking technique. The masked message sequence is tracked with a symbolic sequence generated by another skew tent chaotic map. The theoretic and simulation results state that the proposed algorithm has many properties such as high speed and easy implementation and high security. Therefore it is suitable for practical use in secure communication.
