Anduril Industries revealed Monday that it had quietly develop a family of small dual-use unmanned underwater vehicles (UUVs) ...

Distributed acoustic sensing detects disturbances in fibre optic signals to identify underwater threats NATO ... essential in safeguarding global communications. Lane Burdette, a research ...

Furthermore, two-way satellite–ground optical messages are transmitted in parallel with the quantum ones, enabling key distillation and secure communication in real time. During a single pass ...

Abstract: To protect underwater acoustic communications from interception, the exchange of encryption keys is necessary. Since underwater devices can be compromised, generating keys on site is a ...

Researchers also compared the data collected with the two underwater methods with land-based seismometer data. Though on-land seismometers are more sensitive and can measure more types of ground ...

The security and resource consumption of existing privacy-preserving data aggregation schemes are not suitable for application to underwater acoustic communications. To address the above issues, this ...

Modern communication networks rely on optical signals to transfer vast amounts of data. But just like a weak radio signal, these optical signals need to be amplified to travel long distances without ...
