Phys. Rev. Lett. 97, 140502 (2006) [4 pages]Giant Fiber Lasers: A New Paradigm for Secure Key DistributionReceived 27 April 2006; published 6 October 2006 We propose and analyze a new concept for secure key distribution based on establishing laser oscillations between the sender and receiver. Compared to quantum mechanics based systems, our scheme allows for significantly higher key-establishing rates and longer ranges. By properly designing the laser structure, it is possible to increase the difficulty of eavesdropping almost arbitrarily, thus making our scheme an intriguing alternative and a complementary technology to quantum key-distribution systems. © 2006 The American Physical Society URL:
