【摘要】 无线传感器网络具有通信能力有限、电源能量有限、计算速度和存储空间有限、传感器节点配置密集和网络拓扑结构灵活多变等缺陷,不能保证数据信息在传输中机密性,完整性,真实性和时效性。这些缺陷对无线传感器网络的发展极为不利,没有安全可靠的网络传输保证,其在将来的推广中也会大大受阻。这些问题推动了基于ZigBee的安全消息传输的研究。为此,本文从ZigBee网络节点特性和ZigBee通信网的安全机制进行分析和研究,总结出ZigBee消息在应用层的安全传输是问题的关键。因此,提出了一种ZigBee应用层消息安全机制,将无线传感器网络划分为基于簇的分层体系结构,应用了由Diffie-Hellman密钥协商协议扩展的群组密钥协商机制,结合基于CBC模式的DES加密算法,对ZigBee应用层的消息数据进行封装。最后,对本文提出的ZigBee应用层消息安全机制进行实验与分析。本文主要使用CC2530模块组建ZigBee通信网络的硬件平台,并通过接口设备LTC1756和IS07816的硬件接口驱动程序将SAM卡与CC2530模块进行连接,把本文中提出的ZigBee应用层消息安全机制应用到ZigBee通信网络中,并使用CC2531模块和PacketSniffer(包嗅探器)软件对其应用层消息数据的安全传输进行实验与分析,证明了本文中提出的ZigBee应用层消息安全机制的可行性。再对DES软件、DES硬件、基于CBC模式的DES软件和基于CBC模式的DES硬件等几种加密方式的加密效率进行测试与对比。更多还原

【Abstract】 As there are limit ranges to capacity of the wireless sensor network communication, the electricity power, the computing speed and the storage space, and the intensive sensor node configuration, the flexible network topology and other defects. It cannot guarantee the data confidentiality, integrity authenticity and timeliness when in the transmission. These defects are detrimental to the development of wireless sensor networks, secure and reliable network transmission to ensure its future promotion will be greatly hindered. These issues have promoted research that based on the ZigBee security message transmission. For this purpose, in this article from the characteristics of the ZigBee network nodes and ZigBee communication network security analysis and research, summed ZigBee secure transmission of messages in the application layer is the key to the problem. Therefore, a ZigBee application layer message security mechanisms, wireless sensor network is divided into hierarchical cluster-based architecture, the application of group key agreement mechanism extended by the Diffie-Hellman protocol, combined with the principle of the DES encryption algorithm in CBC mode, the ZigBee application layer message data package.Finally, conduct the experiment and analysis for ZigBee application layer message security mechanisms. In this paper, a ZigBee communication hardware platform uses CC2530module, and add SAM card to CC2530module by LTC1756module and ISO7816hardware interface driver, in this article ZigBee application layer message security mechanisms is applied to ZigBee communication network, and uses the CC2531modules and PacketSniffer software of its application layer message data secure transmission for experiments and analysis, and it has proved the feasibility of the proposed ZigBee application layer message security mechanisms. Then, make a comparison in encryption efficiency among the software on DES, DES hardware, DES software in CBC mode and DES hardware of CBC model.更多还原
