Multi-view Web Services as a Key Security Layer in Internet of Things Architecture Within a Cloud Infrastructure

Connected objects are more and more commonly used within different type of organizations in order to collect, summarize and process data of diverse terminals and devices; this concept is called Internet of Things (IoT). One of the major concerns of IoT architectures is the security. In fact, the concept of gathering data from a large variety of objects brought a lot of capabilities and functionalities in terms of decision making, flexibility and improved services. However, it brought also several security issues such as Authentication, Confidentiality and Integrity. In this work we are proposing a new approach of security implementation in IoT architectures; this approach is based on our previous work regarding Multi-view Web services and makes use of the previously proposed mechanisms of dealing with end users needs and access rights. The proposed architecture consists of the introduction of a new security layer that will receive all kinds of messages and requests through the exposed Multi-view Web services, analyze the access rights and messages subscription of the requestor and the object and then relay the request to the appropriate object or service. This architecture can be implemented in a Cloud infrastructure so as to centralize operations, enhance reusability and reach a high level of availability.
