Secure Opportunistic Data Exchange Using Smart Devices in 5G/LTE-A Networks.
Sumit Kumar Tetarave, Somanath Tripathy · 2018
Popularity of smart phones is increasing rapidly with the facility of Internet through 5G/LTE-A networks. Internet helps to share contents and brings about digital activities through smart devices. Meanwhile, it is a challenging task to communicate or access data in absence of the primary network signal. For members of such a disconnected network, the opportunity of data exchange through a visiting smart phone user, would be a prominent solution. However, security in such a scenario would be the major concern due to the possibility of mishandling of users’ data and therefore, data to be exchanged only to authentic users. In this work, we propose a security framework for opportunistic data exchange in cellular networks. We analyze and evaluate the performance of our protocol with existing schemes providing secure data exchange through device-to-device (D2D) communication. Results show that our proposed framework achieves desired security while consuming significantly less communication overhead. Further, the security of our scheme is verified through AVISPA simulator.
