Secure transmission network using chaotic lasers


In this paper, we propose a scheme for multi-user secure data transmission using chaotic lasers. While schemes based on optical chaos are usually restricted to point-to-point transmission, with this new approach, which is derived from the well-known public key cryptography, it is possible to exchange data between any couple of nodes in a network. For each user, a pair of twin chaotic lasers is required, one being held by the user himself and the other by a provider, who is responsible of the network security. The basic two-laser or three-laser schemes of chaotic transmission are then used for secure data exchange, both between two subscribers and between a subscriber and the provider.
