摘　　要：无线传感器网络(WSN)是通过无线通信方式形成的一个多跳自组织网络,是集信息采集、信息传输、信息处理于一体的智能化信息系统。由于其本身资源方面存在的局限性和脆弱性,使其安全问题成为一大挑战。文中分析了无线传感器网络的安全需求、可能受到的安全攻击,给出了防御方法和解决方案。通过安全加密协议、认证流广播和多种密钥机制实现传感器网络的数据机密性、完整性和系统鲁棒性。Wireless sensor network（MSN） is a self-organized network in wireless communication. It is a intellectualized information system integrated with information collecting, processing and transmitting. Due to its source limitations and vulnerabilities, MSN security problem has become a great challenge. This paper analyzes the security requirements and the potential security threats of MSN. The defense techniques and solutions are given. By means of secure network encryption protocol, micro-timed efficient streaming loss-tolerant authentication protocol, localized encryption and authentication protocol, the data confidentiality, integrity, and system robustness of MSN is effectively enhanced.
