Abstract :
In this paper, we numerically demonstrate secure data transmission using ldquotwinrdquo semiconductor lasers in which chaotic dynamics and synchronization are achieved by electrical injection into the laser pair of a common, chaotic driving-signal, obtained by photodetection of the emission of a third chaotic laser.
