Fast convergent key distribution algorithms using a dual quantum channel
This paper presents three new algorithms over a dual quantum channel to enhance the convergence speed of the key distribution process. The proposed algorithms effectively use a dual quantum channel between the communicating entities and, when combined with the proposed selection of the basis, improve the efficiency of the key distribution process as well as deter Eve. With the use of an initialization vector (IV), the proposed algorithm does not necessitate information exchange about the bases between Alice and Bob, thus removing the requirement of the availability of a two-way conventional channel. Simultaneously, it allows the detection of the presence of Eve in real time. Copyright (C) 2008 John Wiley & Sons, Ltd.
