PROPHYLAXE ‑ Providing Physical Layer Security for the Internet of Things
BMBF-Program “IT-Sicherheitsforschung“ FKZ ITSI4-027, Budget: 3,37 Million Euro
conducted at the Fraunhofer Heinrich Hertz Institute
- Joint PHYLAWS & PROPHYLAXE contribution was presented at the ETSI Workshop on Future Radio Technologies focusing on Air Interfaces. It took place on 27-28 January 2016 in ETSI, Sophia-Antipolis, France.
- *5GNOW and PROPHYLAXE have presented results/demonstrators at the GLOBECOM 2014, Austin (TX)!! See here:

PROPHYLAXE exploits physical layer security mechanisms by means of inherent wireless system properties based on the fading nature of wireless channels. Although traditionally seen as a burden the fading nature provides two mechanisms that can be exploited: 1) the channel variations are reliably observable only by the legitimate receiver and 2) the transmitter can adapt to the channel conditions and control resources in a beneficial way. PROPHYLAXE aims to exploit these features and establishes security architecture for the IoT including design of physical layer protocols for advanced security in a heterogeneous or even hostile environment. Information-theoretic performance limits will outline the level of security dependent on the complexity of protocols and signal processing.
PROPHYLAXE will establish a security concept for the IoT with a number of appealing technical and economic features:
- Cost reduction by abstaining from asymmetric primitives entailing high implementation effort, code size and complex chip layout
- Energy efficiency since the communication module is responsible for the key generation
- Universal applicability for different use case with transport-agnostic key generation concept
- Simple handling since key generation is automated and user interaction is not required (“Plug-and-Secure”) Scalability of the concept due to potentially large system dimensioning
- Scalable security due the inherent wireless channel features
- Increased security since control information can be protected (in combination with standard protocols)
- Support of all relevant security aspects (confidentiality, data integrity, authentication) against passive and
The results of PROPHYLAXE will be exemplarily demonstrated and a Proof-of-Concept established focusing on telemedicine, facility management, smart home networks.
