Real Time Service Level Access Restriction using Dynamic OTUP Generation for Improved Security in Cloud

Abstract

The cloud environment has been identified as the keen platform being used by different cloud users and organizations. The data security has been approached with several techniques like password, attribute based approaches and so on. However, they suffer to achieve higher security performance. To improve the performance, an efficient real time service level access restriction scheme which uses dynamic OTUP (One Time User Password) generation scheme. The method maintains different user information which includes the password details of users. Further, the method collects the one time user password initially. With this, the method restricts the user’s service access by generating OTUP in a dynamic way according to different services. The user has been restricted according to the service and OTUP generation methods. According to this, the method estimates service level trust weight (SLTW) to restrict the user. The methods introduce higher security performance and reduces false ratio.
