| Description |
Chaotic synchronization is a potential candidate for a stream cipher cryptosystem. However, many of the proposed schemes do not possess the required security level to be used in real implementations. One of the major threats to such cryptosystems based on chaotic synchronization is the parameter estimation method both in on-line and off-line forms. In this paper we propose a new method of feedback synchronization, in which instead of a single variable feedback, we propose to use a superposition of multiple variable values. As super-positioning is an irreversible computation, it dilutes the information content of the various parameters of the chaotic system. We show in this paper that an identical chaotic system (parameters are same) can still synchronize, while a non-identical system (parameters are different) will fail. We have demonstrated the robustness of the proposed system from well-known on-line and off-line attacks.
