Título: | Bidirectional private key exchange using delay-coupled semiconductor lasers |
Autor: | Porte, Xavier CSIC ORCID; Soriano, Miguel C. ; Brunner, Daniel CSIC ORCID; Fischer, Ingo CSIC ORCID | Fecha de publicación: | 6-jun-2016 | Editor: | Optical Society of America | Citación: | Optics Letters 41(12): 2871-2874 (2016) | Resumen: | We experimentally demonstrate a key exchange cryptosystem based on the phenomenon of identical chaos synchronization. In our protocol, the private key is symmetrically generated by the two communicating partners. It is built up from the synchronized bits occurring between two current-modulated bidirectionally coupled semiconductor lasers with additional self-feedback. We analyze the security of the exchanged key and discuss the amplification of its privacy. We demonstrate private key generation rates up to 11 Mbit/s over a public channel. | Versión del editor: | http://doi.org/10.1364/OL.41.002871 | URI: | http://hdl.handle.net/10261/157752 | DOI: | 10.1364/OL.41.002871 | ISSN: | 0146-9592 | E-ISSN: | 1539-4794 |
