Identity-Based Proxy Signature Multiple-File PDP for Mobile Cloud Computing
Yuan Yuan, Fu Xie · 2017
Provable Data Possession (PDP) schemes which are vital to data-oriented mobile cloud computing security architecture enable users to check the integrity of their data in the cloud efficiently. Due to the limitation of storage space and computing power of the mobile terminals, a new identity-based proxy signature multiple-file data integrity verification scheme called Identity-Based Proxy Signature Multiple-File PDP(IBPS-MPDP) for mobile cloud computing is proposed. In this paper, by using identity-based proxy signature, the system does not need to take the additional overhead to manage the public key certifications and the mobile users do not need to take additional cost to authenticate others' certificates yet. Allotting the heavy proxy signature tasks to the proxy sign party to implement to reduce the mobile terminal users' computing pressures. Adopting the aggregate signature to diminish the communication overhead of cloud and mobile users. The security of the scheme is proved in the random oracle model.
