Abstract:

The widespread use of cloud computing has made it possible for mobile devices to store and access personal information at any time and from any location. As a result, the issue with data security in mobile cloud systems gets worse and stops them from developing further. Numerous research have been carried out in an effort to enhance cloud security. However, because mobile devices only have limited computational power and resources, the majority of them are not appropriate to mobile cloud. Mobile cloud applications require solutions with minimal computational overhead. A lightweight data sharing system (LDSS) for mobile cloud computing is what we suggest in this research. In order to make it appropriate for mobile cloud settings, it modifies the structure of the access control tree while using CP-ABE, an access control technique often used in regular cloud environments. Much of the computationally demanding access control tree modification in CP-ABE is sent from mobile devices to external proxy servers using LDSS. Additionally, it implements lazy-revocation—a challenging problem in program-based CP-ABE systems—by introducing attribute description fields to lower the user revocation cost. The experimental findings demonstrate that when users share data in mobile cloud settings, LDSS can successfully lower the overhead on the mobile device side.
