Secure Fine-Grained Access Control and Data Sharing for Dynamic Groups in Cloud

Abstract

We propose a secure data sharing scheme for dynamic members in this Secure Fine-Grained Access Control and Data Sharing for Dynamic Groups in Cloud paper. First, we propose a secure way for key distribution without secure communication channels. Second, our scheme can achieve fine-grained access control, any user in the group can use the cloud source, and revoked users can not access the cloud again. Third, we can protect the scheme from collusion attacks, which means that revoked users can not get the original data.

Introduction

Secure Fine-Grained Access Control and Data Sharing for Dynamic Groups in Cloud computing is considered as an alternative to traditional information technology due to its essential characteristics such as resource sharing and minimal operational and maintenance issues. Data storage is one of the cloud service providers that has gained prominence in today’s world because a customer can store their data in the cloud at cheaper costs. The benefit of data storage is, it allows data sharing and access between the group of people in a more secure and consistent way.

From cloud computing, users can achieve an efficient and cost-effective approach to cloud data sharing scheme between group members. It is an advantage of low maintenance and low cost of managing. Meanwhile, since they are outsourced, we provide security guarantees for sharing data files. A secure communication channel is a strong assumption for existing schemes channel and is difficult for practice.
