摘要
简单介绍了量子密码学的发展历史,量子密钥分发基于的量子效应,并主要对文献犤3犦中西安电子科技大学曾贵华、王新梅的量子密钥分发协议改进方案提出一些不足之处,给出了作者自己的改进措施。
The history of development of quantu m cryptography and the quantum effects are intro-duced briefly in this paper.Author p resents some defects in the measures of improvement in the quantum key distribution protocol proposed by Zeng Guihua and Wang Xinmei from th e Xian University of Electronic Science and Technology and then presents her measure of improvement.
