A Layer-Cluster Key Agreement Protocol for Ad Hoc Networks

Mobile ad hoc networks create additional challenges for implementing the group key establishment due to resource constraints on nodes and dynamic changes on topology. The nodes in mobile ad hoc networks are usually low power devices that run on battery power. As a result, the costs of the node resources should be minimized when constructing a group key agreement protocol so that the battery life could be prolonged. To achieve this goal, in this paper we propose a security efficient group key agreement protocol based on Burmester-Desmedt (BD) scheme and layer-cluster group model, referred to as LCKM-BD, which is appropriate for large mobile ad hoc networks. In the layer-cluster group model, BD scheme is employed to establish group key, which can not only meet security demands of mobile ad hoc networks but also improve executing performance. Finally, the proposed protocol LCKM-BD are compared with BD, TGDH (tree-based group Diffe-Hellman), and GDH (group Diffie-Hellman) group key agreement protocols. The analysis results show that our protocol can significantly decrease both the computational overhead and communication costs with respect to these comparable protocols.

基于GPRS的索力监测传输技术研究

文章研究开发了一套基于GPRS技术的无线数据传输系统,远端数据采集模块将索力监测仪的输出信号进行模数转换,通过串行接口驱动无线modem经GPRS网络将数据发送到Internet上的远程监控中心,并完成数据的存储和显示。文章从硬件和软件两方面描述了系统的设计及实现方法,这种新型的数据传输系统非常适合于在边远地区或可移动系统中实现无线的数据采集和传输。     

中国古代"天人合一"思想对构建人与自然关系的启示

社会发展对构建人与自然的和谐关系不可避免地带来了负面效应。“天人合一”思想是中国古人看待人与自然关系的基本态度,其思想内蕴如系统论思想、自然规律思想和协调思想对构建人与自然的和谐关系具有深刻的启示作用。     

航运市场运费套期保值方法探讨

分析研究了2种运费套期保值方法远期运价协议和运价指数期货合约，通过典型案例论证了租船人和船东都能利用这2种方法，锁定运费收入或支出，从而规避运价风险的目的；同时对这2种方法进行了分析比较，指出运价指数期货合约具有灵活性且安全的特点，但二者费用有差异，运价指数期货合约需要一定的保证金，实际费用等于经纪人的佣金(通常为0．3％)加上现金保证金的利息。     

破产和解制度若干问题研究

破产和解制度是破产程序法中的一项重要的预防破产制度,我国现行法律对破产和解有相应的规定,但规定并不完善。本文主要结合破产法最新司法解释《关于审理企业破产案件若干问题的规定》对破产和解的有关规定,具体分析了破产和解的申请主体、申请时间及和解协议是否具有强制执行力等问题,并对司法解释的有关规定加以阐述和评析。
