混沌密码学在过去的几年里得到了广泛的研究。然而,混沌系统的动力学特性降低了混沌密码的安全性,从而阻碍了它们的应用。为了解决这个问题,本文首先提出了安全混沌系统(SCS)的动力学特性,使他们有用的安全密码的建设判别准则,然后讨论了一类混沌系统,数字动态滤波器(DDFs),满足SCS标准。在此基础上,提出了一种基于DDF的伪随机比特发生器(DDF-PRBG)。理论分析和仿真结果表明,DDF和DDF-PRBG满足SCS准则,具有良好的密码学特性。因此,SCS准则和DDF参考模型可以用来克服潜在的混沌系统的动力学特性所带来的问题,提高混沌密码的安全性。
Chaotic cryptography has been widely investigated in the past few years. However, the undesirable dynamical properties of the underlying chaotic systems degrade the security of chaotic ciphers and thereby discourage their applications. To address this issue, this paper first presents discrimination criteria for secure chaotic systems (SCSs) whose dynamical properties make them useful for the construction of secure ciphers and then discusses a class of chaotic systems, digital dynamical filters (DDFs), that meet the SCS criteria. Then, a DDF-based pseudorandom bit generator (DDF-PRBG) for constructing stream ciphers is proposed. Theoretical analysis and simulation results demonstrate that both the DDF and the DDF-PRBG, which satisfy the SCS criteria, have desirable cryptographic properties. Consequently, the SCS criteria and the DDF reference model can be used to overcome the problems caused by the dynamical properties of the underlying chaotic systems and increase the security of chaotic ciphers.
