A new workshop paper will be published next month. This biology-inspired computer science work shows how data be can secretly hidden in a cyber-physical system. We exemplify two data hiding techniques for CPS using smart buildings.

Cyber Physical Systems (CPS) have raised serious security concerns and thus have been subjected to intensive security research lately. In particular, recent publications suggest that there is a potential to transfer hidden information through CPS environments. In comparison to these existing studies, we demonstrate that CPS cannot only be used to covertly transfer secret data but also to store secret data. Using an analogy to the biological concept of animal scatter hoarding behavior we show sow to perform CPS secret data storage in smart buildings.
