无线传感器网络中一种分布式安全存储方案

摘要

After investigating on data storage of wireless sensor networks (WSN) ,we propose an efficient distributed data storage scheme for data storage-centric wireless sensor networks. In traditional centralized data storage scheme, the center node becomes the bottle neck, and thus the compromise of the center node will make the entire network functionless. With our scheme, the above problem is easy to resolve. Our scheme encrypts the data with Reed Solomon Code,and authenticates the data with Message Authentication Code( MAC) ,which makes it possible to re construct the data even when some nodes are dead or compromised. Moreover, our scheme can prevent malicious nodes to forge data, and our scheme can save storage space. The simulation results illustrate the effectiveness of the proposed scheme.%对无线传感器网络的数据存储进行分析和研究,提出了一种以数据为中心的无线传感器网络中的分布式数据存储方案.该方案可有效解决集中式数据存储方案造成的中心节点的高负荷瓶颈问题,同时也避免了由于中心节点失效导致的数据丢失或泄漏问题.相对于现有的分布式数据存储方案,该方案运用Reed Solomon Code对数据进行加密,并且运用消息认证码进行认证.即使部分节点失效时仍能恢复原始数据,并且能避免恶意节点的数据伪造,确保了数据安全,同时也能更好地节省存储空间.通过模拟将该方案和现有的方案进行了比较,验证了该方案具有很好的效果.
