摘　　要：无线信道的广播特性使得其中的碰撞现象普遍存在,充分利用这一特性的物理层网络编码可较大幅度地提高系统吞吐量,但也存在其特有的安全隐患。本文的主要贡献:从物理层网络编码的原理出发,挖掘了其中存在的必要前提破坏、信号强度攻击、信号能量攻击等安全隐患,并提出了应对的基本思路;综述了物理层网络编码的研究现状,并展望了未来的研究方向;提出了结合利用云计算和网络编码构建从终端到交换节点、从底层到高层、无处不在的计算网络的概念。Because of broadcast nature of wireless communication,collision is popular in wireless network.Utilizing the existing interference of different signals received concurrently,physical-layer network coding（PLNC）can significantly improve the throughput of system.However,there are some special security problems for PLNC at this same time.This paper contributes this following：based on analyzing how physical layer network coding to run,some security problems,such as destroying requirement, amplitude attacks,energy attacks,are digged out,and one basic solution is showed to deal with them.Up-to date related issues of PLNC schemes and future trends will be discussed.One thinking which integrate cloud computing with network coding is proposed.Its core idea is to construct one everywhere,terminal-switch,down-top,computing network.
