Transportation systems begin to receive widespread attention from scientific community and emerged towards Intelligent Transportation Systems (ITS), where there is closed loop interaction between vehicles/drivers and the transportation infrastructure empowered by cooperative V2X communications. While some of the enabling technologies are entering their mature phase, e.g., traffic flow sensors and IEEE 802.11p, there is still the need of a complete integrated solution that can take the most

Furthermore, safety, efficiency and comfort ITS applications exhibit tight latency and throughput requirements, for example safety critical services require guaranteed maximum latencies lower than 100ms while most infotainment applications require QoS support and high data rates. Besides latency and throughput, safety applications also require deterministic communications (real-time) and vehicles involved in accident should be granted timely access to the wireless medium to transmit warning messages, even in congested road scenarios. Therefore, European Alliance for Innovation (EAI) took a step towards the realization of Future Intelligent Vehicular Technologies based on dependable and real-time communication and invite both academic and industrial research community by organizing Future 5V conference in Porto, Portugal. Future 5V is an annual international conference by EAI (European Alliance for Innovation) and co-sponsored by Springer. Future 5V received more than 50 research articles in field of Vehicular networks/communications covering theory and practices in the after mentioned field of study. The call-for-papers of this SI was an outcome of the 1st EAI International Conference on Future Intelligent Vehicular Technologies, IoT-BC workshop and open submission. We believe that the accepted papers have a good representation of the after-mentioned research field. The first paper of this SI is "Centralized Group Key Establishment Protocol without a Mutually Trusted Third Party" by Chingfang Hsu et al. The authors have eliminated the need of a mutually trusted key generation center by assuming that each user only trusts himself. This is done by the process during the registration as each user acts as a KGC to register other users and issue sub-shares to other users. From the secret sharing homomorphism, all subshares of each user can be combined into a master share. The master share enables a pairwise shared key between any pair of users. A verification of master shares enables all users to verify their master shares are generated consistently without revealing the master shares. In a group communication, the initiator can become the server to select a group key and distribute it to each other user over a pairwise shared channel. The proposed design is unique since the storage of each user is minimal, the verification of master shares is efficient and the group key distribution is centralized.
