Secure Data Transmission Techniques for Privacy Preserving Computation Offloading Between Fog Computing Nodes

With the advent of technology to digitize the world, an increase in the storage & computational power to store and process the data requirements of the consumers brought Cloud Computing in existence. But computation on cloud is expensive and continuous expansion of this field leads to an arising security concern. This led to the creation of Fog Computing, a layer that transcends the barrier between cloud and edge devices, that operates on most of the end user’s data at the lower level itself, minimizing the data sent to the cloud, hence reducing the computational cost and ensuring more security. There are still some prevalent issues in the basic foundations of the Fog Layer that pose a threat in its functionality. This paper proposes a unique architecture that solves some of the fundamental privacy and security issues of Fog Layer without affecting its baseline performance and efficiency. The architecture relies on establishing a layer of Data-Tables over the communicating nodes and a novel Encryption Procedure encompassed within the data transfer mechanism. The objective is to ensure a smooth flow of computation and data transfer while providing the necessary privacy and security standards which is quite essential nowadays in the paradigm of Fog Computing.
