Security Issues and Challenges in Vehicular Big Data Network (VBDN): A Survey

1. VANET Security Research Group (VSRG) Security Issues and Challenges in Vehicular Big Data Network (VBDN): A Survey Dr. I.A.Sumra

2. Outline • Introduction of VANET • Applications • Safety Application • Non-safety Applications • Current challenges and issue • Security issue • Big Data Issues and challenges • Possible Solutions • Conclusion • Q&A 2

3. IntroductionProblem-1 (Road Accident) 3

4. Intro.. Problem-2 (TrafficJam) 4

5. Intro.. 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. Road Side Unit (RSU) V2R V2V V2V Basic VANET Architecture 5

6. 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!!! 6

7. Security High Mobility Trust Privacy Current VANET Challenges Location Awareness Incentive Scale of Network Real Time Guarantee 7

8. Security • Security is one of the most important issues in vehicular network. Applications of vehicular network should be secure and user receives right information while traversing along their journey. • User, vehicle and road side unit (RSU) are some components of trusted vehicular network. If any of these components of network unexpectedly change their behavior then it would signify that there is a breach of trust in the network. Security Trust Control Attackers and Attacks in network All Components of the network work Properly Privacy Secure User Personal information 8

19. Trusted Platform Module (TPM) • Trusted Platform Moduleis a hardware chip designed for secure computing and can be measure the integrity of the system. • It is basically a piece of hardware and needs software to communicate with it to protect and store data in secure location. • Capability of protection, measurement of integrity and reporting the integrity of data are the key features of TPM module. It can resist software attacks and cost of this module is lower as compared to other security module (Tamper Proof Device). 17

22. Conclusion • VANET generate the huge quantity of data for special functions like (increase the car speed, high mobility of node, location, expansion). • The Data exchange in excess of VANETs frequently plays an imperative function in traffic safety and very strict security necessities are to be accomplished. • Big data has quickly residential into a hotspot topic that magnetize great concentration from academia, industry, and yet governments because growing of data day by day. The 5Vs (Volume, Velocity, Variety, Variability) of big data are the attribute of big data and • In this survey paper, discuss in detail the security issues and challenges in Vehicular Big Data Network (VBDN) and provides the detail description that use of some VANET technologies is to approve that which big data technologies is better for VANET. 20
