The term “Smart Home” is to be understood as the part of the Internet of Things that will increasingly influence the daily lives of users in their own homes. There are many technical approaches and standards on how to connect devices within the home and to the Internet, but no technology has yet taken a lead in the market.

Against this background, there is the opportunity to introduce robust IT security in cooperation with the practice partner Power Plus Communications AG in an early stage of the developement of products and standards. Since all smart home applications are “human-centered”, this must also hold for the IT security used there.

Two PhD projects deal with this topic in the context of the tandem “IT security in Smart Home networks in conjunction with Smart Metering systems”. In addition, a close cooperation with the tandem CONSENT is planned. Both tandems have thematic overlaps in the Smart Home and Smart Grid areas, from which meaningful synergy effects can be derived.
