PROJECT TITLE :

Secure Authentication in Cloud Big Data with Hierarchical Attribute Authorization Structure - 2017

ABSTRACT:

With the quick growing demands for the large knowledge, we tend to need to manage and store the massive knowledge within the cloud. Since the cloud is not absolutely trusted and it will be accessed by any users, the info within the cloud could face threats. During this paper, we propose a secure authentication protocol for cloud big data with a hierarchical attribute authorization structure. Our proposed protocol resorts to the tree-based signature to considerably improve the safety of attribute authorization. To satisfy the massive data requirements, we tend to extend the proposed authentication protocol to support multiple levels within the hierarchical attribute authorization structure. Security analysis shows that our protocol can resist the forgery attack and replay attack. Additionally, our protocol can preserve the entities privacy. Comparing with the previous studies, we have a tendency to will show that our protocol has lower computational and communication overhead.
