【摘要】 自从BB84量子密钥分配协议提出以来,量子加密技术得到了迅速发展,以加密技术为基础的量子信息安全技术也得到了快速发展。为了更全面地、系统地了解量子信息安全技术当前的发展状况和以后发展的趋势,文中通过资料查新,以量子加密技术为基础,阐述了量子密钥分配协议及其实现、量子身份认证和量子数字签名、量子比特承诺等多种基于量子特性的信息安全技术的新发展和新动向。更多还原

【Abstract】 Quantum information security technology,based on the cryptographic techniques,has been made a great progress since quantum key distribution protocol has been proposed.In order to understand it clearly and completely,in this paper we discuss some problems about quantum information security,such as quantum key distribution,quantum identification,quantum digital signature,and quantum bit commitment.Also,we present the trends and new developments.更多还原
