A novel security scheme for Body Area Networks compatible with smart vehicles

The growth of Body Area Networks (BANs) has caused significant academic and industrial research attention, as the concept of BANs provides a feasible solution for real-time health condition monitoring. Meanwhile, Vehicle Area Networks (VANs) support communications in smart vehicles and intelligent traffic systems. In practical situations, the two areas overlap in multiple circumstances and their combination could offer a variety of services that benefit from their complementary nature. The rapid development of BAN and VAN requires advanced security techniques to protect communications since both BANs and VANs are transmitting increasingly mission-critical and private data. Therefore, a novel security scheme consisting of enhanced authentication and encryption solutions, which is dedicated in the overlapping area of VAN and BAN, is proposed in this paper. The key aspects of the security scheme were implemented and evaluated in a Field-Programmable Gate Array (FPGA). The evaluation results illustrate that the proposed security scheme has the advantages of low power consumption, low latency, and low resource utilization.
