Abstract

The field of data management has been reformed by the Cloud computing technologies which offered valuable establishments and amended the storage restrictions barriers for its users. In large enterprises the cloud has been extensively used for implementation due to its benefits. There are still lot of security threats for the data in the cloud. The data owners suffer from its privacy issues which are considered as one of the major concerns. Data privacy can be secured by employing some of the existing methods such as Attribute-based Encryption (ABE). Yet, the security issues are prevailing largely over the cloud. In this research a secured data access control is proposed using the Advanced Encryption Standard (AES) combined with a weighted attribute-based Encryption (AES-WABE). To encrypt the data, the access control policies are used and weight is assigned according to its significance of each attribute. The outsourced data is stored by the cloud service provider and the attribute authority based on the weight that updates the attributes. To minimize the computational overload the data file is accessed by the receiver corresponding to its weight. The proposed procedure provides resistance for collusion, multiple user security with control of fine-grained access based on protection, reliability and efficiency. On concerning the data collaboration and confidentiality, the performance rating is done related with the Cipher-text Policy–Attribute-based Encryption (CP-ABE) and the hybrid attribute-based encryption (HABE) scheme, access control flexibility, limited decryption, full delegation, verification and partial signing.

Highlights

Enormous amount of data can be handled by the storage of cloud which is considered as a magnificent service having effective techniques
The cost of computation is calculated for encryption and decryption
When a request is made by the authenticated user, the consumer based on its weight receives the corresponding files in an encrypted format

Summary

Introduction

Enormous amount of data can be handled by the storage of cloud which is considered as a magnificent service having effective techniques. Personal and business data’s can be stored using this facility, due to this factor lot of enterprises, establishments and individual users use it. The multi-regional, multi-domain and extensive data sharing can be recognized by the cloud storage. There are lot of advantages in the cloud storage service, the main issue in it is the security. Different geographically distributed data centers has access to the stored information in the cloud in database of the cloud the data of the user will not be under the user’s control. The cloud user faces privacy and data confidentiality problems while using cloud computing [3]
