本文从身份认证的角度切入,提出了一种适用于云计算环境下的基于动态口令和生物特征的身份认证方案。本方案利用GSM网络,通过短信途径获取动态口令,使用密码学技术将用户生物特征等信息加密后发送到云端进行身份验证,并且消除了对用户注册地点和登录地点的限制,更加适用于云环境。 This article from the perspective of identity authentication, proposed a suitable for cloud computing environment based on dynamic password and biometric identity authentication scheme. This scheme uses GSM network to obtain dynamic password via SMS, encrypts the user’s biological characteristics and other information using cryptography, and then sends the encrypted data to the cloud for authentication, and eliminates the restriction on user registration location and login location, which is more suitable for cloud environment .
