MUMBAI, India, Nov. 28 -- Intellectual Property India has published a patent application (202531106189 A) filed by National Institute Of Technology, Patna, Bihar, on Nov. 3, for 'secure maritime communications via passive ris aided hybrid satellite-terrestrial networks.'
Inventor(s) include Singh, Pooja; Agarwal, Akash; and Kumar, Preetam.
The application for the patent was published on Nov. 28, under issue no. 48/2025.
According to the abstract released by the Intellectual Property India: "A secure maritime communication system/ method via PRIS (passive reconfigurable intelligent surfaces) and Hybrid Satellite-Terrestrial Maritime Networks (HSTMs, 100) are disclosed. A PRIS-equipped ship, having a PRIS panel, is configured to establish a link with a satellite, a terrestrial base station for receiving signals carrying secure maritime information for ships which are in proximity to the PRIS equipped ship. The PRIS panel applies phase shift(s) for directing said signals towards an intended ship from the PRIS-aided ship. The signals are modulated using Walsh Hadamard Based Spread Orthogonal Frequency Division Multiplexing scheme by the satellite, the terrestrial base station for transmission. Further, an artificial noise (AN) is injected in the signals in such a way that the AN is generated in a null space of a desired channel that remains futile for the intended ship from the PRIS-aided ship and degrades reception of the spy ship."
