微电子机械系统(MEMS)技术的最新进展推动了无线传感器网络(WSNs)的部署。受传感器节点能量存储能力的限制，在无线传感器网络的数据采集中，综合考虑安全性和能效是至关重要的。具有秘密共享的不相交多径路由方案被广泛认为是保证信息安全的有效路由策略之一。这种方案将每个分组转换为多个份额，以增强传输的安全性。然而，在多对一的无线传感器网络中，共享节点很有可能通过同一条链路而被对手拦截。本文将基于秘密共享的多径路由问题描述为一个优化问题。我们的目标是在能量受限的情况下最大化网络安全和生命周期。为此，提出了一种安全节能的三阶段不相交路由方案(SEDR)。在秘密共享算法的基础上，SEDR方案在前两个阶段分散、随机地在网络上分发共享，然后将这些共享传输到汇聚节点。理论和仿真结果表明，在不降低网络生命周期的前提下，我们提出的方案在单黑洞和多黑洞两种情况下都能显著提高网络安全性。
Recent advances in microelectromechanical system (MEMS) technology have boosted the deployment of wireless sensor networks (WSNs). Limited by the energy storage capability of sensor nodes, it is crucial to jointly consider security and energy efficiency in data collection of WSNs. The disjoint multipath routing scheme with secret sharing is widely recognized as one of the effective routing strategies to ensure the safety of information. This kind of scheme transforms each packet into several shares to enhance the security of transmission. However, in many-to-one WSNs, shares have high probability to traverse through the same link and to be intercepted by adversaries. In this paper, we formulate the secret-sharing-based multipath routing problem as an optimization problem. Our objective aims at maximizing both network security and lifetime, subject to the energy constraints. To this end, a three-phase disjoint routing scheme called the Security and Energy-efficient Disjoint Route (SEDR) is proposed. Based on the secret-sharing algorithm, the SEDR scheme dispersively and randomly delivers shares all over the network in the first two phases and then transmits these shares to the sink node. Both theoretical and simulation results demonstrate that our proposed scheme has significant improvement in network security under both scenarios of single and multiple black holes without reducing the network lifetime.
