摘要:

本文针对传感器网络提出了一种基于多路径的安全数据传输方案,通过在多条路径上分发数据,达到增强机密性和鲁棒性的目的。针对数据机密性,设计基于异或计算的编码方式,使得攻击者解析任何数据片段的难度等同于攻占所有的K条路径。针对传输的鲁棒性,设计了数据分发算法以及备份与校验相结合的容错模式,实现了容忍多条路径失效的数据传输,并且具有适度的数据冗余、理想的路径利用率以及快速的数据恢复能力。

关键词: 传感器网络 多路径 数据传输 安全

Abstract:

By distributing data on multiple paths,we propose a secure data transmission scheme with privacy and robustness for sensor networks.For privacy,we give a coding scheme on the XOR operation to strengthen the data confidentiality so that it is so difficult as occupying all the paths for a attacker to uncover anything of the information.For robustness,we design a prepared distributing algorithm and a fault-tolerant mode which combines backup with checkout,and realizes the data transmission which tolerates multipath's drop with moderate data redundancy,ideal path utilization,and quick data recovery.
