Abstract big data collection in large scale

Abstract : Internet of things is the network of devicesconnected to the Internet, including vehicle, wearable devices,and almost anything with a sensor on it. These things collectand exchange data.Internet of vehicles enables information exchange and contentsharing among vehicles. IoV offers several benefits such asroad safety, traffic efficiency, etc. by forwarding up-to-datetraffic information about upcoming traffic. And big datacollection can improve decision making, especially pathplanning in IoV. But malicious users in IoV may mislead thewhole communications. How to secure the big data collection inlarge scale IoV is meaningful and deserves researching.

In an IoV architecture, initially vehicles need to register in thebig data centre to connect into the network. Afterward,vehicles associate with big data centre via mutualauthentication and single sign-on algorithm. The business datais transferred in plain text form while the confidential data istransferred in cipher text form.

Cryptographic hash function is a mathematical algorithm thatmaps data of arbitrary size to a bit string of fixed size. Whichis a one way function. Only way to recreate the input from anideal cryptographic hash output is to attempt a brute forcesearch of possible inputs to see if they produce a match 8.However, the existing protocols in the related area cannot bedirectly applied in big data collection in large scale IoV.

As aresult, the security and efficiency issue for big data collectionstill deserves research.III. DRAWBACKS? Less scalability:? The capability of a system, network, orprocess to handle a growing amount of workis less.? Data falsification attack:? Data can be falsified by unauthorized access.? High delay? Secure Data StorageIV. METHODOLOGYA.

• Infrastructure as a Service :- Basic IoV-and traffic-relatedcomputing services are based on the cloud framework,including vehicle/traffic status data storage, area-basedvehicle monitoring/control, vehicle safety statusmonitoring/control, real-time traffic analysis, and accessbilling and settlement. Meanwhile, as a core capability, openAPIs are provided to any third-party application developerto help them rapidly build related application services.• Platform as a Service – Includes bulk GPS data and GIDdata processing, ITS holographic data processing, cloudstorage, information mining and analysis, informationsecurity, and data buses.

• Software as a Service :– Through basic cloud services andthird-party service resources, any developer may createcertain applications that support IoV and ITS from variousterminals 9.VI.
