    A Location-Based Cryptographic Suite for Underwater Acoustic Networks
    (Springer, 2023) Harsha, T.S.; Katasani, V.S.; Partani, R.; Chandavarkar, B.R.
    Communication in underwater acoustic networks (UANs) is plagued by resource constraints and environmental issues. In this chapter, we present a novel key generation algorithm based on the geolocation of sender and receiver nodes and then design a lightweight, 10-round iteration block cipher algorithm for UAN communication. Using theoretical analysis, our algorithm should resist brute-force searches for adversarial attacks, such as failure of one sensor node does not affect the whole topology. In essence, it adds a second layer of security by combining geolocation with the encryption algorithm. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
