Securing Communication Channels in IoT using an Android Smart Phone

In today's world, smart devices are a necessity to have, and represent an essential tool for performing daily activities. With this comes the need to secure the communication between the IoT devices in the consumer's home, to prevent attacks that may jeopardize the confidentiality and integrity of communication between the IoT devices. The life cycle of a a simple device includes a series of stages that the device undergoes: from construction and production to decommissioning. In this thesis, the Manufacturing, Bootstrapping and Factory Reset parts of IoT device's life cycle are considered, focusing on security. For example, the Controller of user's home network (e.g., user's smart phone) should bootstrap the ``right'' IoT device and the IoT device should bootstrap with the ``right'' Controller. The security is based on device credentials, such as the device certificate during the bootstrapping process, and the operational credentials that are provisioned to the IoT device from the Controller during the bootstrapping. The goal of this thesis is to achieve easy-to-use and secure procedure for setting up the IoT device into a home network, and for controlling that IoT device from an Android mobile phone (Controller). The objectives are: (1) explore the different aspects of using a smartphone as a Controller device to securely manage the life cycle of a simple device; (2) propose a system design for securely managing the life cycle of a simple device from a Controller compliant with existing standards, (e.g. Lightweight Machine to Machine (LwM2M) is an industrial standard used to manage and control industrial IoT Devices); (3) implement a proof of concept based on the system design; (4) provide a user-friendly interface for a better experience for the user by using popular bootsrapping methods such as QR code scanning; (5) discuss the choices regarding securing credentials and managing data, and achieve a good balance between usability and security during the bootstrapping process. In order to achieve those goals, the state-of-art technologies for IoT device management were studied. Then an Android application that uses LwM2M standard in consumer's home setting was specified, designed and implemented. The Android application is wrapped in a smooth user interface that allows the user a good experience when attempting to connect and control the target IoT device

Strong Electronic Identification: Survey & Scenario Planning

The deployment of more high-risk services such as online banking and government services on the Internet has meant that the need and demand for strong electronic identity is bigger today more than ever. Different stakeholders have different reasons for moving their services to the Internet, including cost savings, being closer to the customer or citizen, increasing volume and value of services among others. This means that traditional online identification schemes based on self-asserted identities are no longer sufficient to cope with the required level of assurance demanded by these services. Therefore, strong electronic identification methods that utilize identifiers rooted in real world identities must be provided to be used by customers and citizens alike on the Internet. This thesis focuses on studying state-of-the-art methods for providing reliable and mass market strong electronic identity in the world today. It looks at concrete real-world examples that enable real world identities to be transferred and used in the virtual world of the Internet. The thesis identifies crucial factors that determine what constitutes a strong electronic identity solution and through these factors evaluates and compares the example solutions surveyed in the thesis. As the Internet become more pervasive in our lives; mobile devices are becoming the primary devices for communication and accessing Internet services. This has thus, raised the question of what sort of strong electronic identity solutions could be implemented and how such solutions could adapt to the future. To help to understand the possible alternate futures, a scenario planning and analysis method was used to develop a series of scenarios from underlying key economic, political, technological and social trends and uncertainties. The resulting three future scenarios indicate how the future of strong electronic identity will shape up with the aim of helping stakeholders contemplate the future and develop policies and strategies to better position themselves for the future
