Entwicklung einiger Verschlüsselungsalgorithmen mit chaotischen Funktionen

In today's information society, cryptography has become one of the most important tools for data protection, trust, access control, electronic payments, corporate security, and countless other areas. The primary goal of cryptography is undoubtedly to achieve confidentiality. In recent years, there has been intensive research into a new source of information security: chaotic functions. Our project aims to make a step forward in the field of chaotic-based cryptography for data confidentiality. We will present three different encryption algorithms. The first two are block ciphers. They will be explained in detail, and we will discuss the original versions of the algorithms, their weaknesses, and the proposed improvements. For the first algorithm, the proposed improvement focuses on speed, while for the second algorithm, the proposed improvement targets security. For the third algorithm, which is examined in this project, we will present its properties and investigate its implementation on FPGAs using VHDL.
