无线传感器网络匿名通信技术研究进展

信息安全(内容安全和通信安全)一直是无线传感器网络(WSN)研究与应用关注的热点.由于传感器节点能量、计算和内存限制以及部署环境的特殊性,WSN难以适用复杂度高的安全算法.内容安全可通过加密方法和认证机制来实现,而匿名通信技术是实现通信安全与隐私保护的一种有效方法.通过对传统匿名通信技术和WSN匿名通信机制的调研,分析了WSN关键匿名通信技术的优缺点,并进行了总结和展望.

Anonymous Communication Technology for Wireless Sensor Network:a Survey

In wireless sensor network (WSN),the information security that involves contents security and communication security becomes the hotspot of research and application.Since the limitation of sensor nodes' resource (energy,computation,et al) and deployment in diverse environments,some complex security algorithms are hardly implemented for WSN.The content security can be realized by various existing encryption approaches and authentication mechanisms,and the anonymous communication technology is a good way to achieve the communication security.The article is to provide a general overview of the anonymous communication in WSN and cover all the relevant work,providing the interested researcher pointers for open research issues in this field.The traditional anonymous communication technologies and WSN's anonymous communication schemes is investigated and reviewed.Furthermore,the advantages and disadvantages of key anonymous communication technologies is analyzed and summarized in WSN.
