Collusion-Resistant and Time-Aware Co-Verification for Edge Data Integrity

This research proposes CTCV, a framework to verify that data stored on edge nodes (computers positioned between users and distant servers for faster access) hasn't been corrupted or tampered with. The framework uses blockchain (a distributed ledger technology) to let edge nodes check each other's data integrity without relying on a single trusted auditor, while preventing collusion attacks (where multiple nodes work together to hide data corruption) through careful verification methods and time limits on response times.
