u-blox has filed a patent for a method to protect transmitted payload data via a one-to-many communication channel. The method involves generating public and receiver device keys, creating a provider key, and distributing an envelope for secure data transmission. Receiver devices decrypt and authenticate the protected payload data using the receiver key. GlobalData’s report on u-blox gives a 360-degree view of the company including its patenting strategy.

Method for protecting payload data in one-to-many communication
The patent application (Publication Number: US20240031144A1) describes a method for protecting payload data transmitted through a one-to-many communication channel from a provider device to multiple receiver devices. The method involves generating a public key set supporting asymmetric bilinear pairings, generating receiver device keys based on this public key set, distributing these keys securely to the respective devices, generating a provider key and an envelope, distributing the envelope to the devices, generating a receiver key at the receiver device, encrypting or signing the payload data using the provider key, distributing the protected payload data, and processing it at the receiver device by decrypting or authenticating it. The method ensures secure transmission and protection of data through the communication channel.
Furthermore, the patent application includes additional claims related to the generation of receiver keys, the order of cyclic groups, the generation of constant numbers for the public key set, the repetition rates for key generation, the use of a Hash-Key Derivation Function for key derivation, and the storage and distribution of keys by a trusted entity. The method also involves the use of computer-readable media storing instructions for executing the operations, a provider device, a receiver device, and a communication system for implementing the secure data transmission process. The system ensures that the public key set, receiver device keys, provider key, and envelope are generated and distributed securely, enabling the protection of payload data during transmission and processing at the receiver end.
