An Improved Scheme of B92 Protocol and Digital Signature
Bao Xiao-min
Abstract
An improvement of B92 quantum key distribution protocol is proposed in this paper.The main idea is to find secret listeners more easily from a trap of the quantum channel by some false basis the sender has inserted.Based on the quantum key distribution protocol of B92 and the RSA public-key cipher system,a new dual safekeeping and mutually authenticated digital signature scheme is constructed.
