Based on a university’s practice in upgrading its network management platform, presents a visual analytic system which integrates network topological space,IP space and network geographical space into a collaborative solution to help network administrators address difficulties in locating end user and troubleshooting. Throughout the development cycle, we worked alongside with users to clarify their actual demands and habitual operations through scenario application, interviews and a variety of evaluation. This user-centered approach guides us step by step to apply cyber security visualization and visual analytic technology to actual use.

量子游走已经被提出可以用于瞬时地传输量子比特或多维量子态。根据量子游走的隐形传输模型,该文提出一种无需提前准备纠缠源的基于正则图上量子游走的仲裁量子签名算法。在初始化阶段,密钥是由量子密钥分发系统制备;在签名阶段,基于正则图上的量子游走隐形传输模型被用于转移信息副本密文从发送者到接收者。具体地,发送者编码要签名信息的密文在硬币态上,通过两步正则图上的量子游走,可以自动地产生用于量子隐形传输必须的纠缠态。发送者和接收者对制备的纠缠态的测量为签名生成和签名验证的凭据。在验证阶段,在仲裁的辅助下,验证者依照发送者的经典结果核实签名的有效性。此外,随机数和认证的公共板被引进阻止接收方在接收真正信息序列之前的存在性伪造攻击和否认攻击。安全性分析表明设计的算法满足签名者和接收者的不可抵赖以及任何人的不可伪造。讨论表明方案不能抗击发送者的抵赖攻击,相应的建议被给出。由于实验上已经证明量子游走可以在多个不同的物理系统上实现,因此该签名方案未来是可实现的。
