| Abstract: | In this paper,a chaotic encryption algorithm based on the disturbed Lorenz system is proposed.Firstly,the Lorenz system parameters b is disturbed by using the Legendre polynomial in order to compensate the degradation behavior of chaotic systems due to the computer’s finite precision,then the plaintexts are encrypted by using the pseudo-random sequence which are produced by the disturbed Lorenz system.As a result,the algorithm can effectively resist all known attacks and make information more secure.The proposed algorithm is described in detail,along with its security analysis and implementation.Theoretical analyses and computer simulations both confirm that the new algorithm possesses high security and fast encryption speed for practical information encryption. |
