A Secure And Scalable Data Sharing Using Key Aggregate Cryptosystem

Suvarna Vijay Somvanshi, Santosh Kumar

Abstract


Today, gaining popularity privacy for accessing outsourcing
data stored on cloud is a major issue in cloud computing. In
cloud storage data is stored on single physical machine and
this stored data may shared by multiple users from different
machines. User doesn’t have control on accessing outsourced
data. For identification of leaked data to everyone data access
security or privacy for data is a challenging section. To store
as well for sharing data securely Cryptosystem is used. In
cryptosystem before storing data on cloud user firstly encrypt
data then placed it on cloud. And then data decryption is
performed when user want to access it. This task may require
multiple keys for data encryption as well as data decryption.
In proposed system key-aggregation is implemented on
concept on merging or aggregating the encryption and
decryption key into single one in cryptosystem for sharing of
scalable data. It is very compressed formed of aggregation of
key. In proposed approach unique key can hold multiple keys
that are required. In proposed system concentrate on sharing
data securely, efficiently among multiple users Sharing data
and delegation of data is possible as fixed sized of data blocks
are created. In this proposed system implements Shamir secret
sharing algorithm for securely, sharing aggregate key for
multiple users..
