In the IoTAC project, we are looking at different IoT architectures to identify best practices, potential weaknesses and to understand the difference between the various approaches. Below we give a short summary of four architectures we have analyzed. ISO/IEC Internet of Things (IoT) Reference Architecture ISO/IEC 30141 is an…
Certification ensures that a process or product meets the requirements of a known standard or specification, often audited by an independent third party. Validation ensures that a product meets pre-determined requirement specifications and can be seen as “sub-process” of certification. In both cases, those standards or specifications are usually the…
In recent years the rapid proliferation of Internet-connected devices is driving an unprecedented growth of Internet of Things (IoT) systems and applications. This enables the evolving of the functionalities that they provide to end-users, but also in terms of the technologies that they comprise. Specifically, non-trivial state-of-the-art IoT systems comprise…

The Internet has been steadily growing since its birth back in the second half of the last century. This constant growth was driven by different trends in different epochs. The most recent trend is to connect all sorts of embedded devices to the Internet, including home entertainment systems, industry equipment,…

The Internet of things (IoT) is changing the world right before our very eyes. It can make it safer and more convenient, help conserve resources and efficiently manage entire production lines. The IoT concept encompasses an enormous amount of devices, technologies, software, and data transmission protocols. However, the diversity of…

In my previous post (https://iotac.eu/front-end-access-control-a-new-solution-for-capability-based-access-control/) I was writing about Front-End Access Control, a kind of delegated access control solution for IoT services, which pushes the authorisation function to the user side. Users have their own dedicated secure elements (chip card or Trusted Execution Environment – TEE), which act as a…

According to a large number of research papers, legacy access control systems cannot adequately support IoT requirements. Solutions like Identity Based Access Control (IBAC), Role-Based Access Control (RBAC), Attribute-Based Access Control (ABAC), Trust-Based Access Control (TBAC), just to mention the best-known ones, fall short of providing the necessary functionality and…
