Key Pre-distribution Scheme in Fog Networks with Multi Clouds

Creating a secure communication channel in hierarchical networks is a very important issue and several algorithms have been proposed for it. Unfortunately, due to limited resources in fog networks, which are a special type of hierarchical networks, it is not possible to use conventional algorithms. In this article, we have presented an algorithm to create a secure communication channel on fog networks, which is based on key pre-distribution and is used for multi-cloud fog networks. In this method, by using the SBIBD, blocks are generated to be assigned to the cloud nodes, and by using the residual design on the SBIBD, classes and blocks are created to be assigned to the fog nodes and end devices. The results show that the proposed method increases scalability and reduces communication, memory and computing overheads. The probability of capturing the network in the proposed method is about ۰ and its connectivity is about ۱.
