摘要
随着无线传感器网络越来越多的应用于各个领域,网络安全显得更加突出;为了让具有合法身份的用户加入到网络中,获取相应的服务,同时有效阻止非法用户获取网络信息,确保无线传感器网络的外部安全,则要求网络必须采用用户认证机制,确定用户身份的合法性;文章探讨了无线传感器网络在安全方面存在的问题与挑战,着重研究了当前主要的用户认证方案并分析其主要特点,最后指出了需要进一步研究的方向。
With Wireless sensor networks becoming more widely used for a variety of applications, network security appears much more important to some applications. User authentication as an essential part of the security needs being used to make sure the legality of the us- ers, which can allow users with legal identity to access the network and acquire appropriate service, at the same time, can effectively prevent unauthorized users from learning network information and can ensure the external security of wireless sensor networks, This paper indicates the drawbacks and challenges of wireless sensor networks, focuses on the authentication solutions, analyzes their main features and finally points out the direction for further research.
