本文提出了一种利用混沌激光进行私有数据传输的方案，该方案来源于众所周知的公钥密码学。使用这种新方法，可以在网络中的任何一对用户之间交换数据，而基于混沌激光的方案通常仅限于在两个特定用户之间传输，共享一对孪生激光对。这可以通过引入负责网络安全的提供者来实现。对于每个用户，需要一对双混沌激光器，一个由供应商持有，另一个由用户自己持有。然后，在两个用户之间以及用户与提供商之间使用混沌传输的基本双激光方案进行安全数据交换。基于这种结构，可以考虑几种安排，包括使用电光中继器，本文对此进行了详细研究。更先进的解决方案也可以实现，例如，使用三激光方案。采用Lang-Kobayashi模型进行模拟。实验采用inp集成模块进行。
In this paper, we propose a scheme for private data transmission using chaotic lasers, which is derived from the well-known public key cryptography. With this new approach, it is possible to exchange data between any couple of subscribers in a network, while schemes based on chaotic lasers are usually restricted to transmission between two specific users, sharing a twin laser pair. This is possible by introducing a provider, who is responsible of the network security. For each subscriber a couple of twin chaotic lasers is required, one being held by the provider and the other by the subscriber himself. The basic two-laser scheme of chaotic transmission is then used for secure data exchange, both between two subscribers and between a subscriber and the provider. Several arrangements can be considered, based on this architecture, including the use of an electro-optical repeater, which is studied in detail in this paper. More advanced solutions can be also implemented, e.g., using a three-laser scheme. The Lang-Kobayashi model is used for simulations. Experiments are performed using InP-integrated modules.
