Secure digital communication using controlled projective synchronisation of chaos. (English) Zbl 1068.94010

Chaos Solitons Fractals 23, No. 3, 1063-1070 (2005).
Summary: A new approach to chaos communication is proposed to encrypt digital information using controlled projective synchronisation. The scheme encrypts a binary sequence by manipulating the scaling feature of synchronisation from the coupled system. The transmitted signal therefore embeds only a single set of statistical properties. This prevents cryptanalysts from breaking the chaotic encryption scheme by using characteristic cryptanalysis that aims to detect switching of statistical properties in the intercepted information carrier signal. A pseudo-random switching key is incorporated into the scheme to mask out the deterministic nature of the underlying coupled system.
