Presentation Transcript

  1. VANET Security Research Group (VSRG) Dr I.A.Sumra Using Trusted Platform Module (TPM) to Secure Business Communication (SBC) in Vehicular Ad hoc Network (VANET)

  2. Introduction V A E T N • Vehicular ad-hoc network is a special kind of network in which nodes (Vehicles) can communicate with each other on the road and with its Infrastructure. V2I Road Side Unit (RSU) V2V V2V Basic VANET Architecture 2

  3. Safety Applications Non Safety Applications VANET Applications Work Zone Warning:!!! Work Zone Warning:!!! Work in Progress Plz! use Alt. route Shopping MALL ( TESCO ) Parking Slot Available!!! RSU Parking Slot Available!!! 3

  4. FOUR ASPECTS FOR VANET RESEARCH WORK

  5. 1.Academic Research (AR) • The first aspect of the VANET Security R&D Ecosystem is the Academic Research. Past researchers have contributed a lot of novel ideas in new life saving network. • Vehicular Ad hoc Network (VANET) have been introduced to provide the infrastructure for life saving applications.

  6. 2. Car Manufactures (CM) • The second aspect of the VANET Security R&D Ecosystem is the car manufacturers which form a big and important industry. Researchers proposed and designed the concept of smart vehicle with some special sensors that run using VANET infrastructure. • Smart vehicles are different from the normal vehicles which are fitted with sensors, equipped with processing and communication abilities that can help users access to services using their private information, access to information useful for their journeys, doing business transactions and making decisions.

  7. 3. Govt. Authorities (GA) • The third aspect of the VANET Security R&D Ecosystem is the Govt. Agencies (GA) that is responsible for providing authentication services for users using secure public and private keys, whether permanent or temporary based on the type of services on highway. • GA provides these keys for secure communications between vehicles and infrastructure.

  8. 4. End Users (EU) • Last aspect of VANET Security R&D Ecosystem is end users. • End users have their own security, trust and privacy requirements

  9. PROPOSED SBC MODEL

  10. 1.Govt. Authority (GA) • Govt. authority (GA) is the first module of SBC model and it is responsible to define the security policies and also authentication services to secure the public and private keys. • GA provides these keys for secure communications between vehicles and infrastructure. • Private Trusted Authority (PTA) is also the part of government authorities and it is provided different types of service to serve the users through various types of applications in heterogeneous environment.

  11. 2. Business Parties • Govt. authorities give more benefits for business parties to invest their money in this field. Business parties also consider the user requirements while their journey and provide those services which is more necessary for end users. • There are following three basic components of business parties. • Service Provider (SP) • Security Requirements • Difference Services

  12. 3. TPM - Trusted Platform Module • A smart vehicle has an important role to perform the secure communication in a network and smart vehicle is a combination of several mechanical components with the ability to perform computations. • Security is provided by both the hardware and software working together; however, the most important role in a smart vehicle is played by the hardware. • For secure communication in VANET, the role of these security hardware modules is very prominent and has achieved the maximums level of security in VANET.

  13. TPM with smart vehicle

  14. 4. End User • End user is the last module of business model and purpose of this model to provide entertainments services and makes their journey more enjoyable. • With passage of time user requirement will be change and service provider upgrade their system and meet end user requirements in future vehicular network. • End user has a dynamic behaviour and changes his/her behaviour according to the information received from other users or from the roadside unit (RSU).

  15. WORKING MECHANISM OF SBC • Scenario One: Internet Access Services

  16. WORKING MECHANISM OF SBC • Scenario Two: Toll Collection Services

  17. Conclusion • VANET potential applications directly focus on user’s life on the road by sending some safety messages and non-safety messages. • In propose model it is explained three modules of business model and explain the relationship of each modules. • For successful implementation of business model every module plays their role accurately and serves the end users.
