Abstract
Recently, as vehicle computing technology has advanced, the paradigm of the vehicle has changed from a simple means of transportation to a smart vehicle for safety and convenience. In addition, the previous functions of the Intelligent Transportation System (ITS) such as traffic accident prevention and providing traffic volume information have been combined with cloud computing. ITS services provide user-oriented broad services in the Vehicular Cloud Computing (VCC) environment through efficient traffic management, traffic accident prevention, and convenience services. However, existing vehicle services focus on providing services using sensing information inside the vehicle and the system to provide the service through an interface with the external infrastructure is insufficient. In addition, because wireless networks are used in VCC environments, there is a risk of important information leakage from sensors inside the vehicle, such as driver personal identification and payment information at the time of goods purchase. We propose the VCC Service-oriented Security Framework (VCC-SSF) to address the limitations and security threats of VCC-based services. The proposed framework considers security for convenient and efficient services of VCC and includes new user-oriented payment management and active accident management services. Furthermore, it provides authentication, encryption, access control, confidentiality, integrity, and privacy protection for user personal information and information inside the vehicle.
Highlights
The advancement of Intelligent Traffic Systems (ITS) technology provides functions to prevent accidents for vehicles and pedestrians as well as quickly find destinations
Inter-domain routing selects a vehicle to play the role of gateway for communication among multiple Virtual Cord Protocol (VCP) cords, or decides which protocol to use when data is saved to a local VCP cord
Privacy Protection: Among the information transmitted in the Vehicular Cloud Computing (VCC) environment, privacy protection should be considered for the driver or user identification information, vehicle location information, video or voice recorded by the vehicle black box, payment information used in Payment
Summary
The advancement of Intelligent Traffic Systems (ITS) technology provides functions to prevent accidents for vehicles and pedestrians as well as quickly find destinations. It provides conveniences such as public transportation arrival alarms, among others. VCC-SSF provides the authentication, encryption, access control, and privacy protection required to protect private information, payment, and other important information inside the vehicle from security threats that may occur in the VCC environment. VCC-SSF includes a new active payment service that meets user requirements through the Payment as well as Accident Management Services to actively provide traffic accident prevention and accident response and management.
