Ensuring Cache Data Integrity in Multi-access Edge Computing Environment

This thesis proposes a set of systematic solutions to address the edge data integrity (EDI) problem in the multi-access edge computing environment, with different real-world application scenarios. EDI-V is a lightweight probabilistic scheme verifying massive data replicas with higher efficiency and acceptable corruption detection ability. Second, EDI-s is a deterministic scheme providing a stronger data integrity guarantee. Third, EDI-D is a decentralized scheme solving the EDI problem at the edge server side to minimize the backhaul network traffic. Finally, EDI-H is a hybrid scheme making use of both centralized and decentralized schemes to further improve efficiency and reduce communication overheads.
