Abstract :
Chaotic and classical (binary) stream ciphers are compared with respect to their cryptographical properties. Possible synchronization schemes, algebraic and analytical properties as well as design and implementation aspects are discussed. For two example classes with similar system structures, it is shown that chaotic stream ciphers can achieve a higher level of complexity than classical binary systems due to the algebraic properties of the system structure
