Abstract
6 pages, 1 table.-- Communication presented at the 5th World Multiconference on Systemics, Cybernetics and Informatics and 7th International Conference on Information System Analysis and Synthesis (SCI/ISAS 2001, Orlando, Florida, Jul 22-25, 2001).The advent of quantum computers may compromise the security of today's conventional cryptosystems. Quantum key distribution protocols are proposed to
ward off such threat; but, for the moment, the proposed quantum protocols are an hybrid of classical and quantum mechanisms and, as a consequence, they will result compromised as easily as conventional cryptography by quantum cryptanalysis.This work was supported by CICYT, Spain, under grant TEL98-1020 and by MEC under Programa de estancias de Científicos y Tecnólogos Extranjeros en España.Peer reviewe
