With the evolution of information communication technology, a large number of new applications appear, resulting in kinds of new accessing equipments to be deployed. Since the characteristics of randomness, dynamic and unpredictability of their positions, securely discovering these new equipments is one of a primary challenges to guarantee the security issues for these new applications. Traditional path discovery protocols cannot be directly borrowed and applied onto new service models due to the aforementioned inherent vulnerabilities. In this paper, we propose a Public key infrastructure-based(PKIbased) Trustworthy path discovery mechanism(TPDM),which is further implemented by trustworthy node discovery and neighbor node discovery protocols for new service models. As a result, a source node can discover a trustworthy path to the destination node and each intermediate node can also detect its neighbor nodes. Security analysis and evaluation results indicate the effectiveness and efficiency of our proposed mechanism.

巡航导弹超低空突防效果好、命中精度高、价格低廉,这些优越的性能使其在近几次局部战争中大显身手,越来越受到世界各国的高度重视,也促使各国纷纷研究巡航导弹及其防御措施。国内对巡航导弹的防御研究多从电子对抗与火力打击两方面分别入手,缺乏对巡航导弹的综合防御系统及其仿真的研究。为了更好地研究巡航导弹的综合防御问题,在分析巡航导弹防御方法的基础上,提出构建对巡航导弹进行软硬对抗的综合防御系统,并建立了基于DIS的综合防御系统仿真框架,介绍了系统的体系结构和模型体系,对进一步深化巡航导弹防御研究具有重要的意义。

双沟道AlGaN/GaNHEMT器件在电子限域性、电流运输等方面优于单沟道结构,且能更好地缓解电流崩塌,提高设备的运行能力,在高功率应用中具有重要意义.本文对n-Al_(0.3)Ga_(0.7)N/GaN/i-Al_(x)Ga_(1–x)N/GaN结构中的电荷状态以及运输性质进行研究.通过求解一维薛定谔方程和泊松方程,获得其电势、电场和电子分布,分析了双沟道中二维电子气状态与合金无序散射、位错散射的关系.结果表明,在第一沟道中,当Al_(x)Ga_(1–x)N的Al组分和厚度提升时,二维电子气密度逐渐减小,合金无序散射的减弱使迁移率增大,位错散射增强致迁移率变小,总迁移率主要由合金无序散射决定.在第二沟道中,当Al_(x)Ga_(1–x)N的Al组分和厚度提升时,二维电子气密度随之增大,由于较低的势垒高度以及高渗透电子的作用,第二沟道中的合金无序散射影响更大,合金无序散射迁移率随Al_(x)Ga_(1–x)N层的Al组分和厚度的增加而减少且变化趋势逐渐趋于平缓,位错散射作用的减弱导致迁移率的提升.总体上,第一沟道势阱中受到的位错散射低于第二沟道势阱.随着背势垒厚度的增加,第二沟道中主导的散射机制逐渐从位错散射转为合金无序散射.
