Emerging V2X and IIoT deployment scenarios require high levels of security linked to data privacy and integrity. Traditional centralized cryptographic systems fail however to provide the needed levels of security being often susceptible to impersonation and relay attacks over the wireless environments. To solve such problems and provide protection against attacks we develop ad-hoc key generation and distribution protocols to protect against and detect malicious relays and attacks already at the wireless physical layer level.

V2X wireless applications are prone to often suffer of interference or out-of-range denial-of-service. For such safety critical applications it is highly important to provide fail-safe procedures for these negative scenarios. Our solutions and algorithms aim to mitigate such problems by means of edge-focused advanced signal processing, local caching or ad-hoc routing. We carefully combine and fuse the above strategies and their information extensions to generate different failure domains able to provide minimum requirements of users’ quality of service according to various use cases.
