Koninklijke Philips had five patents in regtech during Q4 2023. The patents filed by Koninklijke Philips NV in Q4 2023 focus on establishing secure wireless links between devices using encryption and public-private key pairs, as well as a cellular communication system supporting a Network Relay Function for managing indirect connections. The method involves sending identifying information over the wireless channel, encrypting it with the second device’s public key, extracting the information with the private key, deriving a session key, and establishing a secure wireless link. The system allows for data transfer via indirect connections with relay service codes, where the Network Relay Function determines and encrypts a different relay service code for enhanced privacy.

Application: Method and device to establish a wireless secure link while maintaining privacy against tracking (Patent ID: US20230362657A1)

The patent application by Koninklijke Philips NV describes a method and devices for establishing a secure wireless link between two devices using a pairing protocol. The first device sends identifying information encrypted with the second device's public key over the wireless channel, which is decrypted by the second device using its private key. A session key is derived based on the identifying information to establish the secure wireless link. The method involves generating random information, using Elliptic Curve Cryptography for encryption, and deriving the session key based on the identifying information, which can be an SAE password identifier as per IEEE 802.11 standards.

The devices described in the patent application include a processor for encryption and key derivation, a transmitter for sending encrypted identifying information, and a receiver for decrypting the information. The devices use public and private key information to establish the secure wireless link based on the identifying information provided during the pairing protocol. The method and devices are designed to ensure secure communication between the first and second devices over the wireless physical channel, with the session key derived from the identifying information, which can be an identifier for a password or passphrase. The devices are also capable of extracting public key information from various frames and using it for encryption and decryption purposes.
