Internet of Things: new Architecture to ensure Robustness, Security and Privacy of IoT Systems

with the rapid development in computing and networking capabilities, a new technology has been emerged known as internet of things (IoT). IoT is a giant network of connected and interacted devices, which collect data and send it using the internet. Today, IoT is playing important role in daily life; it adds intelligence to several domains, such as health care, smart homes and cities, and smart transportation.Nevertheless, several challenges are introduced by the new IoT system requirements, which cannot be adequately addressed by current models and architectures. Security and privacy present the main challenges of IoT, which are more important now than ever, due to the explosive growth of connected devices and the huge amount of generated data. All these challenges really should be taken in consideration. Good reference architecture is the main key to ensure security, privacy and many other emergent requirements, because it presents the functional view of IoT. So, IoT requires new architectures to address these new challenges and face these problems. Therefore, the aim of this paper is to suggest powerful architecture to build secure IoT system, and which guarantees the privacy of all its users. It tries to fulfill the new emergent requirements, and solve the previous challenges. In addition, it explains the role of each part to achieve a robust secure IoT system, and how it contributes in the integration of other technologies.
