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.

一种新的基于密码和基于位置的身份验证密钥交换

基于密码的身份验证密钥交换是用于安全身份验证和密钥交换的流行方法。随着无人机的广泛应用，位置信息也已经成为认证的重要因素。在本文中，我们提出了一种新的密钥交换协议，该协议首先实现了密码和位置的双重身份验证，并提出了两种适用于PPAKE机制的方案：一种是无人机身份验证，另一种是军事身份验证。根据。通过添加位置身份验证，身份验证的可靠性得到了提高，对抗攻击的难度也增加了。任何可以侦听，篡改和发送消息的任意对手都只能对指定位置的密码猜测进行在线攻击。最后，
