无线传感器网络中的“双重”身份验证

如今,无线传感器网络是一种新的和有前途的下一代实时无线监控应用的解决方案。如果在考虑部署传感器网络之前没有适当的安全考虑,可以成为一个威胁。但是,如果有任何安全漏洞,即可能向攻击者敞开了大门并且危害应用。因此,用户身份验证的核心要求之一,以防止未经授权的无线传感器网络的数据访问用户。在这方面提出一个有效的双重身份验证的无线传感器网络,它是基于密码和智能卡（双重）。计划提供了相互认证,使用户能够选择和频繁地改变自己密码。再者,通过合理计算成本,提供强大的保护防止不同类型的攻击。

Two factor user authentication in wireless sensor network

Nowadays, wireless sensor networks （WSNs） are appeared to be new and promising solutions for next generation real-time wireless monitoring applications. These WSNs could become a threat if suitable security is not considered before the deployment. However, if there is any loophole in security, that might opens the door to attackers and hence, endanger for the applications. So, user authentication is one of the core requirements to protect WSNs data access from the unauthorized users. In this regard, this paper proposes an efficient two-factor user authentication for WSNs, which is based on password and smart card （two-factors）. The scheme provides mutual authentication, enables the user to choose and change their password frequently. Moreover, they provides strong protection against different kind of attacks at reasonable computation cost.
