Integrity of semiconductor laser chaotic communications to naïve eavesdroppers.
The integrity of a chaotic encoding technique based on an external-cavity semiconductor laser transmitter-receiver system is experimentally examined. A semiconductor laser placed in the transmission path of the system is used to represent an eavesdropper intercepting a chaotic communication. The eavesdropper is able to obtain a copy of the transmission but is unable to decode the message. A chaotic communication system based on external-cavity semiconductor lasers is seen therefore to be secure against this form of interception.
