Efficient Client-side Deduplication Of Encrypted Data With Public Auditing In Cloud Storage

Efficient Client-Side DE duplication of Encrypted Data with Public Auditing in Cloud Storage

Abstract:

At present, there is a considerable increase in the amount of data stored in storage services, along with dramatic evolution of networking techniques. The aim of the project is to reduce the cloud storage space by using the technique DE duplication of encrypted data and audit the files in cloud with the help of third party auditor to find the status of file in cloud regularly. In storage services with huge data, the storage servers may want to reduce the volume of stored data, and the clients may want to monitor the integrity of their data with a low cost, since the price of the functions related to data storage increase in proportion to the size of the data. To achieve these goals, secure DE duplication and integrity auditing delegation techniques have been studied, In this, we design a combined technique which performs both secure DE duplication of encrypted data and public integrity auditing of data. To support the two functions, the planned theme performs challenge response protocols using the BLS signature based holomorphic linear authenticator. We utilize a 3rd party auditor for performing public audit, so as to help low-powered clients. The proposed scheme satisfies all the fundamental security necessities. We additionally propose two variances that provide higher security and better performance.
