Indra Sistemas S.A. have designed and developed a safety and secure solution system for the rail transportation environment based on a distributed architecture under the domain of the Industrial IoT that enables V2V, V2I, and I2I communications, allowing peer-to-peer data sharing. UPM has designed and implemented a HW-based security infrastructure for extreme edge devices in IoT. The implementation takes advantage of HW accelerator to enhance security in low resources devices with a very low overhead in cost and memory footprint. Current security solutions are problematic due to centralized control entity. The complexity of this kind of system resides in the management, in a decentralized way, of the security at each point of the distributed architecture. This chapter describes how the system secures all the infrastructure based on a distributed architecture without affecting the throughput and the high availability of the data in order to get a top-performance, in compliance with the strengthen safety and security constrains of the rail environment's regulations.
