To improve the security features of chaotic communication system,a chaotic encryption scheme was developed based on piecewise parabolic map,and composite sequence was used.The scheme overcomes the limitation of current chaotic map through stochasticly changing the interval division,and the complexity of chaotic sequence was improved.Simulations on image encryption show that the scheme has excellent security features to fight back some kinds of attacks,and enlarges the key space.
