摘要
对量子密钥分配的B92协议做了一些改进,即通过令发信方Alice故意公布一些假的测量基提高诱使窃听者Eve现身的概率并基于改进的B92协议和RSA加密体制提出了一种双向认证签名方案.
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.
