Secure and Efficient Attribute-Based Access Control for Multiauthority Cloud Storage

Abstract

Secure and Efficient Attribute-Based Access Control for Multiauthority Cloud Storage Data access control is an efficient way to provide data security in the cloud, but the data access control in cloud storage systems becomes a challenging issue due to data outsourcing over untrusted cloud servers.
 
Secure and Efficient Attribute-Based Access Control for Multiauthority Cloud Storage (ABE) technique is considered to be the most trustworthy cryptographic conducting tool to ensure direct control by data owner on their data in public cloud storage. The previous Secure and Efficient Attribute-Based Access Control for Multiauthority Cloud Storage schemes involve only one authority to maintain the complete set of attributes, which can create a single-point hindrance to both security and performance.
 

Introduction

Cloud storage is an important cloud computing service offering data owners services to host their data in the cloud. Project on Secure and Efficient Attribute-Based Access Control for Multiauthority Cloud Storage new paradigm of data hosting and data access services poses a major challenge to data access control.

Because the data owners can’t fully trust the cloud server, this was solved using the previous methods ‘ attribute-based encryption. The data owner defines access policies in the previous method and encrypts data by policies. 

Adequate method of cryptography is used to achieve secure cloud data transaction. The data owner must store in the cloud after encryption of the file. If a third person downloads the file, they can view the record if they have the key to decrypt the encrypted file.

Cloud computing is one of the emerging technologies to overcome the problem, which contains a huge open distributed system. It is important to protect user data and privacy.
