Evaluation and Implementation of a Secure Zero Configuration IoT System

Sammanfattning: The Internet of Things (IoT) comprises a large number of heterogeneous devices. It is forecasted that up to 50 billion devices will be connected to the Internet by 2020. All of them have to be configured. Due to the heterogeneity of devices and the enormous increasing number of devices, manual configuration becomes more and more complex and inefficient. Zero configuration is put forward to solve this problem, which makes device configured automatically without additional manual involvement. Besides that, there are many security threats we want to avoid in the future. These security problems include unauthenticated nodes accessing to IoT data, denial of service, lack of confidentiality, malicious attack from hackers and so on. This paper studies the characteristics of IoT firstly and then highlights the implementation of zero configuration and security to IoT. This paper describes the underlying features of zero configuration and primary requirements of security, as well as finds some related mature technologies, based on that proposes a concise solution – combining the Bonjour and many security approaches for implementation of a secure zero IoT system. In addition, this solution is implemented in a small environment scenario of IoT, a smart home. All the programs are in Java language. Evaluation and conclusion are done in final phase.
