针对传感器网络不仅有更多的攻击方式,而且可以采用的防御手段也极为有限的问题,文章从安全协议的设计角度出发阐述了无线传感器网络存在的安全问题并有针对性地提出了解决方法。在详细分析SPINS[1]协议安全特性的基础上指出了该协议尚存的安全问题,并对协议进行了有效的改进。
For the sensor network not only more attacks, but also the defense methods that can be used are also very limited. This paper describes the security problems of wireless sensor networks from the perspective of the design of security protocols and puts forward some solutions. Based on the detailed analysis of the security features of the SPINS [1] protocol, the security issues existing in the protocol are pointed out, and the protocol is effectively improved.
