SECURE DATA SHARING IN AWS CLOUD ENVIRONMENT

Abstract

The main aim of this paper is to provide secure data sharing to authenticated users by the data owners by checking authorization. As it is effective and low-cost management, cloud-based data storage services have the interest in both academia and industry in recent years. Service providers must utilize secure data storage and sharing mechanisms to maintain data confidentiality and service user privacy because they deliver service through an open network. Encryption is the most widely used for protecting sensitive data from being hacked. However, simply encrypting data (for example, using AES) is insufficient to meet the actual need for data management. Also, effective access control over download requests must be considered to prevent Economic Denial of Service (EDoS) attacks from preventing users from using the service. In this work, we look at secure cloud-based storage, in the sense that we create a control mechanism that can handle both data access and download requests while holding security and efficiency using an attribute-based encryption algorithm. Keywords: Cloud, Economic Denial of Sustainability (EDOS), Advanced encrypted standard(AES), Denial of Service(DOS).
