An Efficient Authentication System to Access Electric Vehicle Data in The Cloud Based on Identity Role-based Access Control

Security is one of the main considerations in choosing file storage media. Cloud server is one of storage mediums that provides virtual resources to users through third party and it can be accessed through the Internet connection. Cloud computing has several advantages, such as ease to access, ease to control, user-friendly to operate, and flexible capacity. However, these advantages cause potential security problems such as data breach attack. Therefore, a strong security system becomes important to overcome the losses caused by these security problems. A solution to increase the security level is utilizing cryptography algorithms. Due to the discovery of several loopholes in the traditional cryptosystems, the concept of using Computational Deoxyribonucleic Acid (DNA) cryptosystem was identified as a possible more complex cryptosystem to solve. Meanwhile, Role-based Access Control (RBAC) provides efficient and strong ways to manage authorization of the system resources based on user authentication. By cooperating with Identity-based Cryptography (IBC) and DNA cryptosystem, we propose an efficient authentication system to securely access electric vehicle (EV) data stored in the cloud server based on identity-based RBAC.
