SECURE COMMUNICATION SYSTEM BASED ON MULTISTABILITY

Secure communication system based on multistability. A secure communication system based on multistability consisting of transmitter/receiver based on multistable chaotic oscillators and two public/private communication channels is disclosed. The private allows synchronizing the transmitter and receiver oscillators. Identical chaotic switches in emitter and receiver change the initial conditions of the oscillators discreetly with intervals shorter than the synchronization time, functioning as secret keys allowing the change of chaotic attractors simultaneously in the emitter and receiver oscillators. The information is transmitted through the public channel, adhering a very large number of information signal packets in a staggered manner to a very large number of multistable chaotic masking signals within the same time series. The change of the chaotic attractors faster than the synchronization time makes the synchronization attack impossible, and in addition the synchronization of chaotic signals between the sender and receiver in each attractor allows the information signal to be recovered with high stability.
