Although it makes appreciable development, there are still uncertainties about security concepts of its usage that is usually considered as a major concern in the design of IoT architectures. This paper presents a general survey of all the security issues in IoT along with an analysis of IoT architectures. The study defines security requirements and challenges that are common in IoT implementations and discusses security threats and related solutions on each layer of IoT architecture to make this technology secure and more widespread accordingly.展开更多
