Abstract: A new encryption method based on combining two chaotic systems of good randomness is proposed .The security of initial values, system parameters and superposition coefficients of the two chaotic systems are utilized. The algorithm has high calculate speed and very little cost of time and space . Simulation results show that the cryptosystem can resist attacking of system identification , and the ciphertexts encryption effect is well .It is very fit those secure communication situations of resource restricting and high real-time requirement.
