On the Features and Challenges of Security & Privacy in Distributed Internet of Things

In the Internet of Things, services can be provisioned using centralized ar-chitectures, where central entities acquire, process, and provide information. Alternatively, distributed architectures, where entities at the edge of the network exchange information and collaborate with each other in a dynamic way, can also be used. In order to understand the applicability and viabil-ity of this distributed approach, it is necessary to know its advantages and disadvantages – not only in terms of features but also in terms of security and privacy challenges. The purpose of this paper is to show that the dis-tributed approach has various challenges that need to be solved, but also various interesting properties and strengths
