IntactEdge: Secure Multi-Replica Data Integrity Verification in Mobile Edge Computing

Lingshuang Liu, Liang Xue, Xiangman Li, Xuemin Sherman Shen

Abstract: In this paper, we propose a new secure data integrity verification scheme for mobile edge computing (MEC), named IntactEdge, which provides an efficient method for end users in MEC to verify that the edge servers correctly maintain their stored data. Particularly, IntactEdge is designed using lightweight cryptographic mechanisms, such as message authentication codes and hash functions, to ensure efficiency in generating and verifying data integrity proofs. Batch verification is also supported to further enhance computational efficiency for end users during integrity checks. In addition, IntactEdge offers the desirable feature of multi-replica secure storage, allowing user data to be distributed across multiple edge servers to enhance data availability. To prevent edge nodes from exploiting data replicas stored on other nodes to falsely satisfy integrity verification requests, IntactEdge generates distinct data replicas for different edge nodes, while still enabling each replica to support proof generation using the same authentication tag. Finally, we demonstrate that IntactEdge is secure against potential data integrity attacks on edge servers and highly efficient in both tag generation and integrity verification.
