Abstract:

In Cloud architecture, the storage systems can be centralized and decentralized environments. Centralized storage systems stored data in private cloud, maintained in a single location, can be accessed by one or more user, whereas in decentralized storage system, the data is stored on more than one or multiple servers. Users or companies are being a part of the decentralized cloud storage cloud to host the servers. The data may be stored on any server, i.e., no dedicated server for data storage and which can be accessed easily. In decentralized storage system, the files are stored and protected with the help of blockchain technology. Blockchain is nothing but a chain of blocks (computers or servers), which are connected by using cryptography. Each block contains a set of transactions which has been encrypted and shared in a secured way among multiple servers. Blockchain technology ensures confidentiality and integrity, which can be implemented by using peer-to-peer network. In this paper, we discussed how the technology improves security used by different applications in distributed environment. Further, we proposed adaptive encryption algorithm to improve security and access control.
