提出一种基于移动设备的USB Key身份认证方案,主要用于解决在移动设备端传统身份认证技术中存在的安全问题.在移动设备端使用USB Key身份认证技术可以很好地提高移动设备对用户身份认证的安全性.主要从两方面进行论述:移动设备端是如何获取USB Key中的数字证书并进行身份认证,从而保证移动设备环境下的安全;移动设备端的用户是如何进行身份认证,从而保证应用服务的安全性.通过安全性分析和实验可得出,这种身份认证技术可有效地抵御移动设备端账户和服务攻击.%A USB Key authentication scheme based on mobile devices is proposed,which mainly uses to solve the security problems existing in the traditional identity authentication technologies of mobile devices,and improve the security of user identi-ty authentication. There are two important aspects to be discussed in this paper:how to obtain the digital certificate in USB Key and authenticate user identity by mobile devices,so as to ensure the security in the environment of mobile devices;how to au-thenticate the identity by users of mobile devices to guarantee the security of mobile application services. The security analy-sis and experiment show that the identity authentication technology can effectively resist the attack to the accounts and service of mobile devices.
