Internet of things: Architecture, security challenges and solutions

Internet of things (IoT) is a large distributed network in which billion of devices are interconnected. It is considered to be the largest wave of resolution as it does not require human to machine interaction. However, with the rapid growth of IoT, challenges in terms of security have evolved as well. Since IoT consists of three layers perception layer, network layer and application layer, this paper will provide an analysis for various security problems at each layer including the cross-layer heterogeneous integration security issues and suggest some promising solutions.
