A Password-Based Secure Communication Scheme in Battlefields for Internet of Things

Mobile Ad hoc NETwork (MANET) is a part of the Internet of Things (IoT). In battlefield communication systems, ground soldiers, tanks, and unmanned aerial vehicles comprise a heterogeneous MANET. In 2006, Byun et al. proposed the first constant-round password-based group key exchange with different passwords for such networks. In 2008, Nam et al. discovered the shortcomings of the scheme, and modified it. But the works only provide the group key. In this paper, we propose a password-based secure communication scheme for the IoT, which could be applied in the battlefield communication systems and support dynamic group, in which the nodes join or leave. By performing the scheme, the nodes in the heterogeneous MANET can realize secure broadcast, secure unicast, and secure direct communication across realms. After the analyses, we demonstrate that the scheme is secure and efficient.
