Our research focuses on our core area of expertise in secure and private communication and networking. In this field, federated approaches are usually better suited than centralized ones, as they can provide the user-friendliness of a professional service without locking the user into a single provider and its walled-garden service. By providing compatibility with existing systems, the threshold of entry can be made very low, and by using specialized, minimally invasive solutions to guard security and privacy, it is frequently possible to increase both security and efficiency at the same time.
