Ensuring Privacy Preservation Access Control Mechanism in Cloud based on Identity based Derived Key

Abstract

Cloud computing is a dominant technology that involves massive amounts of data storage and access via the internet. Because there is a large amount of data stored in data centers, it is critical to implement appropriate access control mechanisms over data stored in a cloud. Today, there are numerous access control mechanisms available to provide confidentiality, privacy, and data origin authentication in a cloud environment. The available access control techniques may have a higher computational overhead and lack security concerns. In this paper, we designed and implemented a privacy-preserving access control in cloud computing using derived key identity-based encryption. The proposed method may reduce computational overhead while generating the key while also increasing the robustness of cryptographic keys. During the key generation pro-cess, the trusted key canter (TKC) is involved. The experimental results show that the proposed method reduces computational overhead and provides an easy way to implement an access control mechanism in a cloud environment.
