Anonymous Integrity Auditing Scheme Based on Trusted Execution Environment for Distributed Edge Computing

This research proposes ATRIA, a system for verifying that copies of data stored across multiple edge computing servers are authentic and haven't been tampered with. ATRIA uses TEEs (trusted execution environments, which are secure hardware areas that isolate sensitive operations) to shift the work of generating verification tags from resource-limited user devices to more powerful servers, while also protecting user privacy through anonymous identities that a trusted authority can trace if needed. The system protects against attacks where servers collude or create fake data on demand, and testing shows it uses less computing power than similar existing approaches.
