Abstract

Highlights: We find that the map-version table is vulnerable to delete-insert attack, and the existed dynamic structures are not monotonic, then propose a monotonic dynamic structure index logic table. We extend identity-based provable data possession scheme to identity-based non-repudiable dynamic provable data possession scheme by using index logic table. Our proposed scheme is not only resistant tampering cloud returned value attack, hash value stored attack, delete-insert attack and synchronization attack, but also more efficient compared with other schemes. Abstract: In cloud-assisted wearable devices, how to protect the integrity of data stored in the cloud is a hot issue. For the scenes where clients are dishonest, we study the non-repudiable dynamic provable data possession schemes, and find that existing dynamic structures are not suitable for non-repudiable dynamic provable data possession schemes. The Merkle hash tree must be combined with timestamps to construct non-repudiable dynamic provable data possession schemes. This will cause the synchronization problem, and map-version tables cannot resist delete-insert attacks. Therefore, we propose a monotonic dynamic structure, i.e., index logic table. Then, we construct an identity based non-repudiable dynamic provable data possession scheme for cloud storage by using index logic tables. The proposed scheme not only resists the hash value stored attack, the delete-insert attack, and the tampering cloud returned value attack, but also avoids the synchronization problem. Furthermore, the proposed scheme has lower computation cost and storage cost in the dynamic operation process. Graphical abstract:
