Rekeying for Encrypted Deduplication Storage

2016 46th Annual IEEE/IFIP International Conference on Dependable Systems and Networks (DSN), 2016
Rekeying refers to an operation of replacing an existing key with a new key for encryption. It renews security protection, so as to protect against key compromise and enable dynamic access control in cryptographic storage. However, it is non-trivial to realize efficient rekeying in encrypted deduplication storage systems, which use deterministic ...

HEDup: Secure Deduplication with Homomorphic Encryption

2015 IEEE International Conference on Networking, Architecture and Storage (NAS), 2015
Deduplication on encrypted data is a promising trend for both cloud storage providers and subscribers. Data deduplication allows cloud storage providers (CSP) to save storage space by eliminating the copies of the same data. Data encryption can ensure the confidentiality of customer's data both in transit and at rest.

Encrypted Data Deduplication in Cloud Storage

2015 10th Asia Joint Conference on Information Security, 2015
Cloud storage is a remote storage service, where users can upload and download their data anytime and anywhere. However, it raises issues regarding privacy and data confidentiality because all the data are stored in the cloud storage. This is a subject of concern for users, and it affects their willingness to use cloud storage services.

Efficient Cross-User Deduplication of Encrypted Data Through Re-Encryption

2018 17th IEEE International Conference On Trust, Security And Privacy In Computing And Communications/ 12th IEEE International Conference On Big Data Science And Engineering (TrustCom/BigDataSE), 2018
Cross-user deduplication is an emerging technique to ease the burden of cloud storage in big data era by storing only one copy of duplicate data. Efficiency reflects the feasibility and is a basic consideration when applying the deduplication scheme. However, in order to achieve certain level of security, existing works suffer from heavy overhead of ...

Secure Cloud Data Deduplication with Efficient Re-Encryption

2021 International Conference on Intelligent Technologies (CONIT), 2021
After the emergence of the cloud architecture, many companies migrate their data from conventional storage i.e., on bare metal to the cloud storage. Since then huge amount of data was stored on cloud servers, which later resulted in redundancy of huge amount of data.

Encrypted Big Data Deduplication in Cloud Storage

2019
Encrypted data deduplication is an efficient way to solve the waste of resources caused by duplicated data in cloud storage services without the loss of security. In this chapter, we proposed three data deduplication schemes on encrypted big data with flexible data access control, data deletion, and data update.

A Bandwidth-Efficient Middleware for Encrypted Deduplication

2018 IEEE Conference on Dependable and Secure Computing (DSC), 2018
Data deduplication is a vital component of current cloud storage systems for optimized space utilization. However, users cannot fairly enjoy the storage savings of deduplication. Uploading two identical files consumes twice the storage quota from a user's account, but the server may store one file copy only.

Secure Random Encryption for Deduplicated Storage

2017
In Storage Services, Deduplication is used to reduce the data size by eliminating storage of duplicate data. Deduplication is an effective data reduction technique to minimize the storage cost as well as communication cost. However, Deduplication raises significant security issues. Malicious users and semi-trusted Storage Server tries to learn the data

Tunable Encrypted Deduplication with Attack-resilient Key Management

ACM Transactions on Storage, 2022
Conventional encrypted deduplication approaches retain the deduplication capability on duplicate chunks after encryption by always deriving the key for encryption/decryption from the chunk content, but such a deterministic nature causes information leakage due to frequency analysis.

Secure Deduplication Scheme for Cloud Encrypted Data

International Journal of Advanced Pervasive and Ubiquitous Computing, 2019
Cloud storage (CS) is gaining much popularity nowadays because it offers low-cost and convenient network storage services. In this big data era, the explosive growth in digital data moves the users towards CS but this causes a lot of storage pressure on CS systems because a large volume of this data is redundant. Data deduplication is an effective data
