A FUNCTIONAL ENCRYPTION TECHNIQUE IN UAV INTEGRATED HETNET: A PROPOSED MODEL

摘要

In the dense urban scenarios, the data users are increasing at an exponential rate. Owing to an increase in the variety of users, a shift occurred from traditional homogeneous network to Heterogeneous Network (HetNet). But the prime concern of HetNets is to provide better Quality of Service (QoS) parameters to the users. For achieving better QoS results, Unmanned Aerial Vehicles (UAVs) can be used along with HetNets. The HetNet deployed can be assisted by UAV so that the users can be managed properly. However, in HetNets assisted by UAVs, plenty of users and devices are operating. In such a huge variety, intruder nodes can operate very easily and can spread various malicious activities in the network. This makes the overall communication in the network vulnerable to various kinds of security attacks. Hence, to secure this communication, we will be using Functional Encryption (FE) technique that will help to secure the data against the intrusion attacks. In FE technique, the decryption of messages allows the users to learn only about particular information in the message. The need to decrypt the whole message is not required. In this paper, the whole process of implementing FE in UAV-HetNet is proposed in two phases: first one between User Equipment (UE) & Micro Base Station (MBS) and second one between MBS & UAV. The proposed idea will be validated using Automated Validation of Internet Security Protocols and Applications (AVISPA) tool. High-Level Protocol Specification Language (HLPSL) codes will be written for validation. It is expected that after implementation of FE concept UAV integrated HetNet will able to provide secure communication in the dense urban area.
