Enhancing Organization Security using Attribute-Based Encryption for Data Sharing

Priya D. Tangde | A. S. Chhajed

Abstract: The use of cloud computing technology is increasing rapidly and progressively. It provides various useful and essential services like data sharing, data storage. Organization can select services as per their requirement. While sharing of data in cloud security is an important aspect. Anyone can share their data in the cloud, but while sharing the data security is one of the challenging issues. The data can be protected from unauthorized person by encrypting it with proper key and should not able to access the private data. For this reason we need to take care of private data by implementing data protection techniques like cryptography. So as to make the data highly secured, the data are stored in encrypted format within the cloud. In this system our work is based on Attribute based Encryption. It is one of the techniques that are more suitable for storing data with encryption. The proposed scheme solves the key escrow problem. The proposed scheme solves the key escrow problem which dealt with key revocation mechanism. In the key revocation process of this system the users key validity is removed. Paillier Cryptosystem is utilized for encryption of keys for assignment and revocation process while Twofish algorithm is used to encrypt and decrypt stored data of users.
