无线传感器网络中分布式数据存储的安全设计方案
首发时间:2009-05-27
摘要:在无人看管的无线传感器网络(Wireless Sensor Networks)中,感应到的数据被存储在本地或指定节点,用户可以根据自己的需要来访问数据。这种模式可以通过便宜而且大的闪存存储器来改进能源的效率和系统的稳健性。然而,分布式数据存储的安全性和可靠性对于这种无线传感器网络的应用至关重要。本文中,我们通过运用秘密共享和Reed-Solomon码,提出了一个安全和可靠的数据存储方案。这种方案有计算安全性,同时也保证了最佳的数据大小。最后通过深入的分析证明了这个方案在无线传感器网络中节点妥协和随机错误存在的情况下可以提供安全和可靠的数据存储。

A Scheme for Secure Distributed Data Storage in Wireless Sensor Networks
Abstract:In unattended Wireless Sensor Networks (WSNs), data is stored locally or at designated nodes upon sensing, and users can access it on demand. This paradigm can improve energy efficiency by making use of the upcoming cheap and large flash memory, as well as system robustness. Nevertheless, the security and dependability of distributed storage are critical for the applicability of such WSNs. In this paper, we propose a secure and dependable data storage scheme by taking advantages of secret sharing and Reed-Solomon code, which has computational security and yet maintains optimal data size. The extensive analysis verifies our scheme can provide secure and dependable data storage in WSNs in the presence of node compromise and random failure.
