Abstract: Achieving a secure positioning system is one of the most prominent issues in the field of wireless security. The central task of this paper is introducing a system that is provably secure for sharing the most sensitive data among the users in a peer-to-peer network. In such systems, the geographical position of the users or the nodes in the network plays a vital role in maintaining the security of the entire network especially for defence purpose. Apart from the existing bounded storage models, the system gives a positive result for 'secure positioning problem'. The designing of the proposed system is based on the network, where the public ledger is maintained by all the nodes independently without any central authority. This zero knowledge protocol proposed in this paper makes the search space size to grow exponentially, which is a major challenge for the intruder to prove their position.

TL;DR: Zhang et al. as discussed by the authors presented a new key exchange protocol, which first realized dual authentication for both password and position, and proposed two applicable scenarios for the PPAKE mechanism: one is unmanned aerial vehicle authentication, and the other one is authentication in the military base.
Abstract: Password-based authenticated key exchange is a popular method for secure authentication and key exchange. With the wide application of unmanned aerial vehicles, position information has also become an important factor in authentication. In this paper, we present a new key exchange protocol, which firstly realizes dual authentication for both password and position, and we propose two applicable scenarios for the PPAKE mechanism: one is unmanned aerial vehicle authentication, and the other one is authentication in the military base. By adding position authentication, the reliability of authentication has improved, and the difficulty of adversarial attacks also increases. Any arbitrary adversary who can listen, tamper, and send messages can only perform an online attack for password guessing at a specified position. Finally, we provide security proofs under the defined model.
