A Lightweight Secure Data Sharing Scheme for Mobile Cloud Computing

Abstract

Mobile devices can store / retrieve personal data from anywhere at any time with the popularity of cloud computing. The problem of data security in the mobile cloud is increasing and preventing further mobile cloud development. A Lightweight Secure Data Sharing Scheme for Mobile Cloud Computing There are substantial studies conducted to improve the security of the cloud. Most of them, however, are not applicable to mobile cloud since mobile devices only have limited computing resources and power.

 

A Lightweight Secure Data Sharing Scheme for Mobile Cloud Computing applications are in great need of solutions with low computational overhead. In this paper, we propose a mobile cloud computing Lightweight Data Sharing Scheme (LDSS). It takes CP-ABE, an access control technology that is used in normal cloud environments, but changes the access control tree structure to make it suitable for mobile cloud environments.

Advantages

  • The experiments show that LDSS can greatly reduce the overhead on the client side, which only introduces a minimal additional cost on the server side.
  • Such an approach is beneficial to implement a realistic data sharing security scheme on mobile devices.
  • The results also show that LDSS has better performance compared to the existing ABE based access control schemes over ciphertext.
  • Multiple revocation operations are merged into one, reducing the overall overhead
  • In LDSS, the storage overhead needed for access control is very small compared to data files.
