Secure Mutual Authentication Scheme in Fog Computing: Survey

As fog computing becomes more widespread, security issues become increasingly critical. Mutual authentication between fog nodes and end-users is a crucial part of fog computing security. This review paper presents the recent literature on secure mutual authentication systems in fog computing. The concept of mutual authentication and fog computing and the techniques used are extracted and explained; at the end of the paper. The most prominent technologies used in mutual authentication and fog computing were discussed in detail. This field received great and continuous attention and development to improve mutual authentication and provide high performance and efficiency. The paper may be helpful to researchers in the field of security and improving mutual authentication. Finally, our study aims to assist the prospective researcher by explaining security issues, open challenges, and future scopes in the mutual authentication scheme in fog computing.
