Medical Data Security in Cloud using CP-ABE and ASS.

      Аннотация: Enhancing security through self-containing of data by assigning roles and encryption in cloud pertains to the project which explains the self-protection mechanism in cloud by data. For providing security over the network it is essential for the data to have a protection mechanism which is provided by encryption of data using attribute based encryption and by assigning roles for the users in the network. This mechanism is known as role based access control (RBAC) and cipher text policy attribute based encryption (CP-ABE) which is represented as RBAC-CPABE. This project involves data centric role based access control (DCRBAC) which is dependent on the data objects rather than on the whole of data and thus provides a fine-grained access control capabilities. RBAC-CPABE is based on the cipher-text policy attribute based encryption scheme and provides the similar efficiency and security, which is demonstrated from the security analysis. This project is used for the purpose of providing security to the data over an alien environment, where the servers have the access to the data.
