SecureFog is a comprehensive research project that aims to develop, evaluate and implement security solutions ( algorithms, protocols, APIs) for the Fog layer. The core concept of the Fog layer is to extend the functionalities of the Cloud closer to the end devices to handle the volume, variety, and velocity of IoT data. The project is to offer innovative hardware and software based security mechanism to ensure data integrity, anonymity and authenticity based on the prior research knowledge and experiences with Physical Unclonable Functions, and Physical Layer Security. The proof-of-concept of these novel ideas has been already demonstrated through ongoing BMBF project PROPHYLAXE. The envisioned tasks are to be cooperatively executed by partners  from FU Berlin, PHYSEC GmbH, azeti networks, and TU Berlin. In all, SecureFog targets to build scalable, and flexible security solutions keeping in mind to meet practical requirements for the logistic sector and IoT market.
