Securing underwater communications: key agreement based on Fully Hashed MQV

, 2017
This paper concerns the implementation and testing of a protocol that two honest parties can efficiently use to share a common secret session key. The protocol, based on the Fully Hashed Menezes-Qu-Vanstone (FHMQV) key agreement, is optimized to be used ...

Robust Interference Cancellation of Chirp and CW Signals for Underwater Acoustics Applications

IEEE Access, 2018
We focus on mitigating strong interferences that can jam underwater acoustics emissions aimed for detection or communications. We consider two types of interferences: narrowband like continuous waveform and wideband like chirp. Both the types are assumed
