| Popis: | Since integrity of data on cloud cannot be assured, several clients and users hesitate to upload their crucial data to the cloud, which eventually hinders cloud storage development. One of the biggest challenges with respect to cloud security is to ensure data confidentiality and one of the solutions to this issue can be by restricting unauthorized access to user data stored on cloud. In due course of time much research has been proposed using cryptographic techniques along with access control model(s) to deal with security issues pertaining to untrusted cloud environments. This work illustrates Role-Based access control policies over user data and permits the owner of the data to store it in an encrypted pattern to the cloud, thereby, allowing only permissible roles to access the data. Hence, the proposed work is an amalgamation of Role-Based Encryption (RBE) scheme using Identity and Broadcast based Encryption scheme to ensure data integrity in public clouds. In this paper we discuss the usage of several algorithmic modules that demonstrates how roles are governed by the membership rights, user revocation, encryption and decryption processes. Finally, the proposed model is compared with its peers on the basis of encryption and decryption time. |
