Abstract
In air-to-underwater communications, a two-untrusted-relay transmission scheme is introduced utilizing lossy-forward (LF) relaying. In this setup, two untrusted relays are utilized between an airborne source and an underwater destination for air-to-underwater scenarios, with no direct link between them. Leveraging the unique characteristics of LF relaying, which accepts intra-link errors and consistently forwards decoded sequences from relays to the destination, it ensures reliable and secure data transmission in decoder-and-forward-based networks. To gauge the efficacy of this network design in ensuring security and reliability, a metric termed reliable-and-secure probability is formulated. This metric measures the probability that the underwater destination can successfully retrieve the original message from the airborne source, while ensuring that the untrusted relays remain unaware. Intriguingly, our findings suggest that by maintaining a balanced power distribution between the airborne source and underwater relays, a commendable level of the reliable-and-secure probability can be achieved.
