Efficient Identity-Based Provable Multi-Copy Data Possession in Multi-Cloud Storage

Jiguo Li et al.

Summary: To increase the availability and durability of outsourced data, many customers store multiple copies on multiple cloud servers. Existing PDP protocols mainly focus on single-copy storage and rely on PKI technique, which has security vulnerabilities and high communication/computational costs. In this paper, we propose a novel identity-based PDP scheme for multi-copy on multiple cloud storage servers, achieving both security and efficiency.

SEPDP: Secure and Efficient Privacy Preserving Provable Data Possession in Cloud Storage

Sanjeet Kumar Nayak et al.

Summary: Cloud computing is a paradigm that reduces storage and maintenance costs for data owners, while also posing security risks due to the loss of physical control over data. To address issues of data integrity and privacy, a secure and efficient SEPDP scheme is proposed, extending to support multiple owners, data dynamics, and batch verification with low computational overhead.

Outsourcing Proofs of Retrievability

Frederik Armknecht et al.

Summary: Proofs of Retrievability (POR) are cryptographic proofs used to ensure that users can retrieve their files stored in the cloud at all times. The need for network access and computational resources hinders the wide adoption of POR by cloud users. Outsourced Proofs of Retrievability (OPOR) can reduce user effort and incur minimal overhead on auditors, making them a more efficient option for secure cloud file retrieval.

Certificateless multi-replica public integrity auditing scheme for dynamic shared data in cloud storage

Jaya Rao Gudeme et al.

Summary: This paper presents a Certificateless Multi-Replica Dynamic Public Auditing Scheme for Shared data in cloud storage, addressing integrity and security concerns, supporting shared data dynamics, and enabling secure user revocation. The scheme is proven to be secure against different types of adversaries under certain assumptions and has been shown to be efficient and practical through performance and experimental evaluations.

Data integrity auditing for secure cloud storage using user behavior prediction

Junfeng Tian et al.

Summary: This paper focuses on the core security issue of data integrity in cloud storage, addressing the resource waste caused by invalid auditing through the introduction of user behavior prediction algorithms and proposing the concept of valid auditing. By formalizing a system model and security model, as well as developing a prototype implementation, it improves auditing efficiency and reduces invalid auditing.
