Abstract—Nowadays, cloud computing and IoT devices are widely used and involved in our life. However, the current cloud computing paradigm still have some limitation mainly related to the latency, location, and mobility. Thus, to overcome such limitations, Fog Computing was introduced as an intermediate layer between the IoT devices and cloud computing to providing multiple benefits such as low latency and mobility. However, the security of Fog Computing protocols is still a concern especially those related CoAP protocol. CoAP protocol is still does not have the reliable standards for securing its architecture and there is a huge lack of the main researches on how security can be managed or provided to CoAP. Hence, this paper surveys the CoAP protocol, its architecture, security and different proposed techniques to secure CoAP protocol. The paper provides a solid reference for the Fog Computing and CoAP protocol security as well as it proposed a taxonomy for the literature review to ease understanding all available techniques to secure CoAP.
