摘要：Traditional honeypot is in fact a "passive proactive" defense mechanism because it may lose the value entirely once the adversary has detected the existence of the static trap and bypassed *** work focuses on a Self-Election dynamic honeypot framework which aims to bewilder attackers by coordinating and switching roles periodically to form a huge dynamic *** this paper,we discuss the UDP Spokesman synchronization scheme and the Self-Election coordination method,perform the framework simulation of the dynamic array honeypot with NS2,carry out the prototype implementation by Java,and then validate the effectiveness and feasibility on the simulation and prototype *** promising results of applying this framework to mitigate the effects of attacks are shown and *** work demonstrates that the Self-Election dynamic array honeypot system is feasible and effective for proactive network confrontation.

摘要：The NoC consists of processing element (PE), network interface (NI) and router. This paper proposes a hybrid scheme for Netwok of Chip (NoC), which aims at obtaining low latency and low power consumption by concerning wired and wireless links between routers. The main objective of this paper is to reduce the latency and power consumption of the network on chip architecture using wireless link between routers. In this paper, the power consumption is reduced by designing a low power router and latency is reduced by implementing a on-chip wireless communication as express links for transferring data from one subnet routers to another subnet routers. The average packet latency and normalized power consumption of proposed hybrid NoC router are analyzed for synthetic traffic loads as shuffle traffic, bitcomp traffic, transpose traffic and bitrev traffic. The proposed hybrid NoC router reduces the normalized power over the wired NoC by 12.18% in consumer traffic, 12.80% in AutoIndust traffic and 12.5% in MPEG2 traffic. The performance is also analyzed with real time traffic environments using Network simulator 2 tool.

摘要：本文通过先进的实时原位磁性测试成功揭示了碱金属离子电池中的Li^(+)、Na^(+)、K^(+)的界面空间电荷存储机制.磁性测试结果表明,在FeSe_(2)等过渡族金属材料碱金属离子电池体系中,M^(+)(Li^(+)/Na^(+)/K^(+))和自旋极化电子可以分别存储在M2Se和Fe中,即界面空间电荷存储机制.这说明FeSe_(2)碱金属离子电池的储能机制不仅包含嵌入和转化反应,还包括界面空间电荷存储机制.此外,根据Fe/M2Se界面体系中空间电荷存储M^(+)的能力不同,磁学以及动力学测试结果进一步证明了碱金属离子半径是影响空间电荷存储的重要因素.该研究表明磁性测试是研究过渡族金属基材料的储能机制以及电化学过程中复杂界面效应的一种强有力的分析表征手段,为设计具有大存储容量和高功率密度的先进储能装置奠定了坚实的基础.

摘要：软件定义网络SDN(Software-Defined Network),或称软件驱动网络SDN(Software Driven Networks)是目前数据中心建设的一个很重要的热点技术,它将网络的控制平面和数据平台相分离,为数据中心的网络控制提供了一种全新的解决方案。对SDN的架构进行了分析,对比了不同的SDN/Overlay覆盖技术实现方法,重点介绍了覆盖(Overlay)方案在控制平面的思路和overlay网络如何与传统网络互通的方法。最后探讨了SDN是未来数据中心的发展趋势。
