Holographic encryption system in the Fresnel domain with convergent random illumination
Optical Engineering, 2010A secure holographic system is proposed, based on the principle of two-wave encryption in the Fresnel domain under convergent random illumination. The convergent random wavefront, instead of the commonly used plane wavefront, improves the security of a holographic encryption system, providing better protection from unauthorized users.

Optical image encryption based on interference under convergent random illumination
Journal of Optics (United Kingdom), 2010In an optical image encryption system based on the interference principle, two pure phase masks are designed analytically to hide an image. These two masks are illuminated with a plane wavefront to retrieve the original image in the form of an interference pattern at the decryption plane.

Convergent encryption enabled secure data deduplication algorithm for cloud environment
Concurrency Computation Practice and ExperienceSummaryThe exponential growth of data poses a critical challenge for cloud storage systems. Redundant data consumes valuable storage space and increases infrastructure costs. Data deduplication, a technique for eliminating duplicate data copies, offers a promising solution.

2020 IEEE 17th Annual Consumer Communications & Networking Conference (CCNC), 2020
Conventional encryption schemes are being used over the years for securing outsourced data to cloud. However, this impedes deduplication- the ability to identify and remove duplicate data from storage server. The idea of Convergent Encryption was introduced to overcome this problem which ensures that identical plaintext files will always produce ...

Attribute-Based Convergent Encryption Key Management for Secure Deduplication in Cloud
Advances in Intelligent Systems and Computing, 2020Data deduplication is a methodology for eliminating duplicate copies of data by keeping the single copy of data with proper access policies, instead of maintaining duplicates of the same data. It reduces cloud storage slot and communication bandwidth.

DICE: A dual integrity convergent encryption protocol for client side secure data deduplication
2017 IEEE International Conference on Systems, Man, and Cybernetics (SMC), 2017Message Locked Encryption (MLE) provides a way to achieve deduplication of data over the cloud in a secured and efficient manner. Various cryptographic protocols that are variants of the MLE scheme have been introduced, but they are either vulnerable to poison attack or consume a large amount of bandwidth.

Randomized Convergent Encryption in the Standard Model via UCEs
2015 International Conference on Computer Science and Applications (CSA), 2015In this paper, we instantiate random oracle (RO) H in the Randomized Convergent Encryption proposed by Bellare et al. (Eurocrypt 2013) via a universal computation alextractor (UCE). We prove that if H is UCE secure for statistically unpredictable source, then there constructed RCE[H] is PRV$-CDA (Strong Privacy-Chosen Distribution Attacks) secure in ...

Enhanced Symmetric Convergent Encryption for Secured Data Deduplication in Cloud
Proceeding International Conference on Science and Engineering, 2023Cloud storage is a virtual setting that includes an amazing amount of processing power. The resources are in a state where they can serve users. Cloud data centres are the locations where all of this computing is maintained. In order to produce high-performance computing, the data centre houses a sizable number of powerful computers and servers ...

Enhanced Convergent Encryption Key Generation for Secured Data Deduplication in Cloud Storage
Journal of Physics: Conference Series, 2018 Data deduplication is broadlyfor maintaining asole copy of user's data in cloud storage servers. Data Deduplication is a process of verify that whether the data are already stored in the cloud storage or not and maintain a single copy of data in the cloud.
