摘　　要：由于混沌系统对初值和参数极其敏感,同时还具有非周期性和伪随机性的特点,近来,它引起了密码学领域的广泛关注,并产生出大量富有成效的研究成果。文章讨论并实现了一个改进的Baptista类型的混沌加密系统,它采用椭圆曲线算法做密钥分配,并可同时产生出Hash表以进行消息认证。对该系统的性能测试表明,混沌加密系统和椭圆曲线加密相结合的方案安全性高,且易于软件实现。Chaotic systems are sensitive to initial conditions and parameters,and their trajectories are non-periodic and pseudorandom.In recent years,the researchers of cryptography pay much attention on encryption with chaotic maps and gain many novel results.In this paper,with the Chebyshev map we design and implement an iterative chaotic encryption system.In our encryption system,an elliptic curve algorithm is employed to implement the distribution of key.The testing presents that this type encryption system is secure and easy to be realized by software.
