A New Password- and Position-Based Authenticated Key Exchange

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.

A Secure Three-Party Authenticated Key Exchange Protocol for Social Networks

“…Each of the legal clients stockpiles their scrutinizer calculated from their real key in the database of the isolated trustworthy servers and every client just needs to recall only words of identification i.e., an authentication key with a trustworthy server [10][11][12]. There have already been identified multifarious benefits of the 3PAKE protocols earlier by numerous researchers in past from security perspectives, however, one of the key benefits of this protocol recognized by some researchers is that it offers an easy method for a huge number of client-to-client communication settings, in addition, every client does not demand to recall numerous keys for diverse clients who converse with each other [13][14][15]. Furthermore, the 3PAKE protocol has a wide scope to implement in diverse electronics applications as well as in the social networks to safeguard the confidential information of the clients as demanded in the modern world [16][17][18].…”
