摘    要:无人值守无线传感器网络(UWSN)通常部署在环境恶劣或敌对环境中,在静态汇聚节点(或基站)部署困难的情况下,感知节点无法完成感知信息的实时汇聚传输,需暂时维持感知数据的生存状态。为了增强数据生存的概率,提高感知数据的抗损坏、擦除和篡改能力,重点研究无人值守无线传感器网络中的数据加密生存问题,提出了一种基于中国剩余定理(CRT)多等级秘密共享的可靠数据生存方案。基于网络中节点的信誉模型,设计了节点权重密钥存储机制,增强了数据加密密钥分割存储的有效性,并结合基于中国剩余定理的秘密共享机制,提升了原有数据加密分发和恢复过程的效率。此外,还讨论了基于中国剩余定理的秘密共享方案具有的良好同态性质,并依此设计了子密钥组合运算方案,提高了数据加密生存方案中子密钥运算的安全性,进一步确保了数据生存方案的安全、可靠。

关 键 词:无人值守无线传感器网络  数据生存  中国剩余定理  权重门限秘密共享  同态性质  信誉模型

Abstract:Unattended Wireless Sensor Network (UWSN) is usually deployed in a bad or hostile environment. The deployment of static aggregation node (or base station) is difficult, making real-time information aggregation impossible. Hence the node should undertake the mission of self-sustaining the data temporarily. In order to enhance the probability of data survival, this paper proposed a dependable data survival scheme based on Chinese Remainder Theorem (CRT) weighted threshold secret sharing in UWSN. The scheme built a node reputation model in the network, improving the efficiency and effectiveness of key division, distribution and reconstruction. In addition, this paper also discussed the good homomorphism properties of CRT based multi-secret sharing, and the key combination operation scheme, which further ensures the reliable survival of data.
Keywords:Unattended Wireless Sensor Network (UWSN)   data survival   Chinese remainder theorem   weighted threshold secret sharing   homomorphism property   reputation model
