Retrieving Safe Information for Decentralized Fault Tolerant Military Network

Vehicular ad-hoc network are used in variety of application due to its property to adapt to any application requirement. It also has a key advantage than other networks as it provides mobility. It is best suited for applications which are distributed in nature. Mobile node is internet connected device which is in frequent movement hence its attachment to internet changes frequently.

Military personals carry the wireless device to communicate with each other and also use to retrieve confidential data by exploiting the external storage nodes. As confidential data is transmitted it must be accessible only for authorized users. This report provides authorization by utilizing (CP-ABE). This technique overcomes the key escrow problem which was found previous approaches. It provides authorization based on attributes. Each military personal is provided a separate key for his region. He can retrieve or send data to his own region and other regions data cannot access by him. Thus provides a reliable transmission of data.
