Abstract

Most of the intelligent traffic light (ITL) devices are deployed in public places which are easily accessible by intruders that results various types of attacks. In order to secure the communication between ITL components, hierarchical blockchain based ITL (HBbITL) architecture has been proposed in this work. Proof-of-work (PoW) consensus has been implemented to enhance ITL device security. Elliptic curve digital signatures are employed for integrity of information and efficient processing in constrained resource environments. Among two popular Ethereum consensuses, PoW and proof of authority (PoA) implementation has been carried out for 1, 5 and 10 s, PoA provides higher throughput compared to PoW. Also, it is clear that HBbITL performs better than the public Ethereum blockchain with respect to latency.
