MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202511133314 A) filed by Manipal University, Jaipur, Rajasthan, on Dec. 30, 2025, for 'lightweight checksum-based iot communication method.'
Inventor(s) include Dr Lal Pratap Verma; and Dr Ghanshyam Raghuwanshi.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a lightweight checksum-based communication method for Internet-of-Things (IoT) devices. The present method introduces a novel lightweight checksum algorithm that generates a 32-bit output and achieves high-entropy bit mixing through the incorporation of MurmurHash-based operations. The method significantly reduces computational cost while providing a real-time mechanism for verifying message integrity in resource-constrained IoT communication environments. This allows for near real-time message integrity verification with minimum computing. The method has been validated through simulation, and standards have been drawn for correctness and performance. Overall, the proposed checksum method bridges the gap between performance and security requirements for resource-sensitive IoT applications. Over the last few years, IoT devices have gained significant popularity due to their capability to connect daily objects to the Internet, thereby enhancing automation, operational efficiency, and enabling smart, data-driven decision-making. Each device transmits valuable data to other devices on the network, and this data plays an important role in decision-making. Therefore, verification of data is crucial at the receiver's end. Standard methods such as CRC32 and HMACs are prone to collisions and require huge computational power. The present invention addressed the limitation of the traditional methods."
