Secure Bike Sharing System for Multi-Modal Journey

Bike sharing systems (BSSs) are getting popular in many cities of the world as an integrated part of multi-modal journey due to its flexibility and eco-friendly nature. Future BSSs will have a pool of Internet of Things (IoT)- integrated smart bikes with computation and communication capabilities. Such systems will be able to provide the service providers with real-time and non-real-time information about user demands, bikes and environments for improved quality of services. However, manipulation of logistics data (e.g. showing availability of bikes or parking where none may exist) and mobility operations (e.g. unauthorized tampering with service-related data) may disrupt the whole service. This paper proposes a framework for secure bike sharing service under multi-modal journey environment using symmetric key encryption and digital signature. Our proposal lets a service provider to collect information from stations and external service providers, and communicate with users in a secure way so that the user gets correct information and a quality service. The proposed framework has the potential to offer enhanced quality of service through security features compared to existing systems for multi-modal transport users.
