B-LoT: Blockchain technology for internet of things in intelligent transportation systems

Project website



The B-IoT project, was part of the PETRAS IoT Research Hub, and focused on enabling simple, reliable communications between Intelligent Transportation Systems (ITS) such as automated vehicles, between each other and with their surrounding infrastructure. The project demonstrated the potential of distributed ledgers such as blockchain as a method of security the integrity of these communication systems.

Our specific role was the design and verification of decentralised and blockchain-enabled key and certificate management, and the design of a Pseudonym scheme and Pseudonym swap scheme with demonstrable benefits over existing methods, validated both by simulations and in a testbed involving ITS units called Cohda.


Some of the project outcomes were published in IEEE journals such as:

  1. Blockchain-Based Dynamic Key Management for Heterogeneous Intelligent Transportation Systems.  Published in the IEEE Internet of Things Journal.
  2. Pseudonym Management Through Blockchain: Cost-Efficient Privacy Preservation on Intelligent Transportation Systems. Published in IEEE Open Access.
  3. Paper title: A blockchain based certificate revocation scheme for vehicular communication systems. Published in the Elsevier Next Generation Computer Systems Journal.
