Dynamic Password Verification Method for USER IDENTITY IN CLOUD R&D Environment

With the rapid development of cloud computing, more and more organizations migrate their business to the cloud and begin to use the R&D environment on the cloud. In order to improve the security and efficiency of user authentication and access control in cloud environment, a dynamic password verification method of user identity in cloud R&D environment is studied. Generating a security combination key in the cloud environment, a key matrix was given, and the user identity and the corresponding password were verified. The basic authentication model of user identity was constructed, the authentication categories were classified from the perspective of security and application, and the secure communication between the server and the client was ensured. Innovative verification of dynamic password based on encryption function, receiving and interpreting key content, user identity dynamic password was verified, and the verification speed and convenience were improved. The experimental results show that the initial compression rate of this method is 96%, and when the user authentication information in PC is 20KB, the compression result is 214B. The dynamic password verification time is kept at 0.2 seconds, which ensures the application effect. This proves that this method can provide secure, efficient and flexible authentication services for various cloud service platforms.
