Abstract

In this paper, we propose a lightweight data sharing scheme (LDSS) for different cloud platforms. It adopts CP-ABE, an access control technology used in most of the cloud environments; there are certain necessary changes in the structure of access control tree to make it suitable for portable cloud environments. LDSS moves a large portion of the computational intensive access control tree transformation in CP-ABE from different devices to external proxy servers. Furthermore, to reduce the user revocation cost, it introduces attribute description fields to implement lazy-revocation, which is a thorny issue in program based CP-ABE systems. The experimental results show that LDSS can effectively reduce the overhead on large number of devices when users are sharing data through different cloud environments Neha Fatima | Prof. S. A.
