Enhanced Security through Cloud-Fog Integration

Abstract

Moving data and computation to the cloud is a promising technology in recent years. As the device density increases in the connected world, proper storage in the traditional cloud without security threats is a cumbersome task. Modification and leakage of data is the major threat in adopting cloud computing. Intelligent technologies are needed to safeguard against cyber-attacks. Fog paradigm enables users for data storage, management and network functions closer to them. Fog server introduced as a middle layer between user devices and the cloud to provide more security for uploaded data. It collects and transfers the encrypted data from the user, and apply reed Solomon code for error detection and MD5 hashing for malicious message detection to ensure more security and integrity. This data will be stored in different cloud servers and respective user's fog devices. Thus the combination of cloud with fog computing will ensure integrity, availability and confidentiality of users data.
