Further, BI provides a proof-of-concept to improve trustworthiness in communications by implementing a technique called physical layer security, which involves generating secret keys to pair devices securely. We use a lightweight implementation targeting low complexity IoT systems in terms of computational power and memory. The study evaluates the feasibility of generating these secret keys and analyzes how factors like channel characteristics and design choices impact the speed at which we can create them. Furthermore, we're addressing the presence of passive eavesdroppers and aim to create a reliable protocol that reduces the impact of eavesdroppers to maintain the confidentiality of secret keys between legitimate users.

Besides physical layer security BI is also looking in security and privacy aspects of mission critical communication. Moreover, we are looking on aspects of security automation, i.e. doing research regarding the question to what extend security (design) decisions can be automated based on the current context, e.g., device location and environment.

Thereby, our security and privacy designs are ground in the paradigm of minimal trust assumptions regarding all involved stakeholders.  

Hexa-X-II will work, beyond enabler-oriented research, to optimized systemization, early validation, and proof-of-concept; work will progress from the 6G key enablers that connect the human, physical, and digital worlds, as explored in Hexa-X, to advanced technology readiness levels.
