Its utilization cases are growing in number of fields such as security of Internet of Things (IoT), banking sector, industries and medical centres. Moreover, IoT has expanded its acceptance because of its deployment in smart homes and city developments round the world. Unfortunately, IoT network devices operate on limited computing power with low storage capacity and network bandwidth. Thus, they are extra close to attacks than other end-point devices such as cell phones, tablets, or PCs. This paper focus on addressing significant security issues of IoT and maps IoT security issues in contradiction of existing solutions found in the literature. Moreover issues that are not solved after implementation of blockchain are highlighted.
