Transport and traffic rule violation monitoring service in ITS: A secured VANET cloud application

Vehicular Ad-hoc Network (VANET) cloud, a hybrid technology, provides several computational services to minimize traffic congestion, travelling time, accidents, and environmental pollution. In the proposed work, the concept of VANET cloud is used for helping the regulatory authorities in identifying the vehicles violating the traffic rules through sensors included as part of On Board Unit (OBU). When the vehicle is on fly the sensor values are periodically transferred to the cloud, controlled by the traffic police. A novel concept called Transient Ticket (TT) has been used to minimize the time and the cost of distributing Certificate Revocation List (CRL) to the vehicles. The proposed scheme also ensures utmost verification of identity, authenticity, confidentiality and integrity of the communication parties and messages exchanged. The work has been simulated using NS3 network simulator and Google App Engine (GAE). All the generated keys, TTs and the exchanged messages have been securely stored in the GAE for the ease of accessibility and processing. The results show that the proposed approach consumes very less time with respect to the generation of keys, exchange of messages, verification of authenticity and the generation of TT without compromising security.
