Infineon Technologies had one patents in regtech during Q1 2024. Infineon Technologies AG’s patent filed in Q1 2024 describes a technique for wireless devices to initially connect using randomized MAC addresses and later send an encrypted permanent MAC address for differentiated services. This method involves a device connecting to an access point with a randomized MAC address, receiving a request for a permanent MAC address, determining whether to send it, encrypting the permanent MAC address, and sending the encrypted MAC address to the access point.

Application: Media access control (MAC) address privacy handling (Patent ID: US20240073677A1)
The patent filed by Infineon Technologies AG describes a method for wireless devices to initially connect using randomized MAC addresses and then send an encrypted permanent MAC address for differentiated services. The method involves a four-way handshake process between the access point (AP) and the wireless device, where the AP sends a request for a permanent MAC address to the device, which responds with an encrypted MAC address containing the permanent MAC address. This encrypted MAC address is generated using a pairwise temporal key (PTK) derived from various parameters, including the MAC addresses and nonces exchanged during the handshake.
Furthermore, the patent details the formatting of messages in a key data encapsulation (KDE) format, the inclusion of message integrity codes (MICs) for security, and the generation and encryption of a group temporal key (GTK) for secure communication. The permanent MAC address is indicated as necessary for differentiated services provided by the AP, allowing for Quality of Service (QoS) parameter changes and access control policies based on this address. The patent also covers scenarios where the request for the permanent MAC address is included in beacon frames, probe responses, or other messages exchanged during the handshake process, ensuring secure and efficient communication between wireless devices and APs in a network.
