中文摘要:
      针对信息安全问题,提出一个对信息加密的加密系统。依据混沌学与密码学的紧密联系,首先构造污染混沌动力系统,并且用此系统进行序列加密,基于分段非线性映射与抛物线映射,引入污染系数α构造污染混沌映射,并进行加密算法;给定算法系统不断变化的参数值,使得系统上一轮的迭代结果影响下一轮的初值,从而使系统成为紧密的整体,最终得到密文信息;最后通过相关性、灵敏度、频率测试等各个角度检验本加密算法的有效性。结果表明:该加密算法加密效果良好,密文及算法都可以有效地抵抗攻击。
英文摘要:
      Aiming at the problem of information security,an encryption system to encrypt information is proposed. On the basis of the close connection between chaos and cryptography ,first,a chaotic dynamic polluted system is constructed,and then an algorithm of sequence encryption is carried out.Introducing a pollution factorα,a polluted chaotic mapping is constructed based on segmented nonlinear and parabolic mapping,then an algorithm of encryption is executed by giving constantly changing parameter values,that is,the results of the previous round in the system affect the initial value of the next round,so that the system is a tight whole. And ciphertext is obtained. Finally ,the effectiveness of this encryption algorithm is verified by correlation,sensitivity,and frequency test. Results show that the encryption algorithm has a good encryption effect,both ciphertext and algorithm can effectively resist attacks.
