PROJECT TITLE :

A Pre-Authentication Approach to Proxy Re-encryption in Big Data Context - 2017

ABSTRACT:

With the growing amount of knowledge, the demand of huge information storage considerably increases. Through the cloud center, knowledge suppliers can conveniently share data stored in the center with others. But, one practically necessary downside in massive data storage is privacy. Throughout the sharing method, data is encrypted to be confidential and anonymous. Such operation will shield privacy from being leaked out. To satisfy the practical conditions, knowledge transmitting with multi receivers is also thought-about. Additional a lot of, this paper proposes the notion of pre-authentication for the primary time, i.e., only users with certain attributes that have already. The pre-authentication mechanism combines the benefits of proxy conditional re-encryption multi-sharing mechanism with the attribute-based mostly authentication technique, thus achieving attributes authentication before re-encryption, and ensuring the protection of the attributes and knowledge. Moreover, this paper finally proves that the system is secure and also the proposed pre-authentication mechanism might significantly enhance the system security level.
