Data Integrity Verification for Edge Computing Environments

Mobile edge computing (MEC), is a technology that extends the power of cloud computing to the edge of the end device, with the primary goal of providing faster response times and an optimized quality of service. Given that edge devices are often used by smaller organizations with less computing power, data on the edge are more susceptible to data corruption, which is closely related to uneven resource allocation and uneven security protection. It is therefore particularly important to check the integrity of the MEC to ensure that it is intact, which in turn serves the symmetry of data security protection and facilitates the realization and optimization of symmetry in resource allocation. An integrity verification protocol MEC-P is proposed. MEC-P allows a third-party auditor (TPA) to check data integrity on the edge without violating users’ data privacy and query pattern privacy. We rigorously demonstrate the security and privacy guarantees of the protocol. In addition, this protocol carefully considers the scenarios of single edge node and multiple edge nodes, as well as the complexity of dynamic modifications. Both theoretical analysis and experimental results demonstrate that the proposed protocol is effective.
