摘要

基于混沌的密码学出现于20世纪90年代初，是非线性动力学在混沌状态下的一种创新应用。即使理论上混沌动力学被认为是密码学的一场新革命，但在现实生活中，一个高效可靠的基于混沌的密码系统并没有出现。主要但不是唯一的原因是数字混沌系统的动态退化，这是最近几年非常流行的一个主题。本文提出了一个新的理论背景，证明了基于混沌的加密算法的低效率。更重要的是，在其中一个相关的案例研究中，另一个神话被打破了:基于同步混沌的模拟加密。

Chaos-Based Cryptography: End of the Road?

Chaos-based cryptography emerged in the early 1990s as an innovative application of nonlinear dynamics in the chaotic regime. Even if in theory chaotic dynamics was thought to evolve into a new revolution in cryptography, in real-life an efficient and reliable chaos-based cryptosystem didn't emerge. The main but not the only reason is the dynamic degradation of digital chaotic systems, a subject that became very popular in the last few years. This paper presents a new theoretical background related to this issue that proves the inefficiency of chaos-based encryption algorithms. Even more, in one of the two relevant case studies presented, another myth is demolished: the analog encryption base on synchronized chaos.
