An Improved CPK Identity Authentication Scheme Based on Cloud Environment

Yanyan Song, Jun Qin


When cloud computing technology becomes increasingly mature and the application field is expanded gradually, it becomes the focus of attention to perfect the security mechanism under cloud computing environment. Identity authentication technology has some limitations and particularities when applied to cloud environment. In this paper, a bidirectional identity authentication scheme based on CPK technology is proposed, to resist forgery attacks in cloud computing environment. The role based access control plan is integrated with the combined public key authentication scheme, to strengthen the security of access control model and guarantee the security of cloud computing. Simulation experiments are conducted on the cloud computing simulation platform via the improved CPK identity authentication based on cloud environment. According to the experimental results, this scheme can effectively carry out user identity authentication under cloud environment, and the desired effect is obtained in the experiment.
