Brief explanation

The patent application describes a wireless device and a relay device that communicate using a wireless communication protocol.

• The wireless device can operate in two modes - one where it transmits messages with an IPv6 packet header and an upper layer protocol data unit encapsulated within a layer 2 MAC frame, and another where it transmits messages without the IPv6 header.
• The relay device performs a header insertion service, where it receives messages from the wireless device without the IPv6 header, inserts header information, and retransmits the messages with complete headers.
• The relay device can also filter out acknowledgements received from the server and forward them to the wireless device at a reduced rate.

Abstract

A wireless device (S) includes a radio (R) for communicating via a wireless communication protocol which employs messages constructed as layer 2 MAC frames each including a layer 2 MAC header and a payload. The wireless device is configured to operate in (i) a first mode in which the wireless device transmits messages (N0, . . . , Nn) via the radio each including an IPv6 packet header and an upper layer protocol data unit encapsulated within the payload of a layer 2 MAC frame, and (ii) a second mode in which the wireless device transmits messages (M0, . . . , Mn) via the radio each including an upper layer protocol data unit encapsulated within the payload of a layer 2 MAC frame without including the IPv6 header. A relay device (T) comprises a radio for communicating via the wireless communication protocol which employs messages constructed as layer 2 MAC frames each including a layer 2 MAC header and a payload. In one power-saving aspect, the relay device is configured to perform a header insertion service (I) in which the relay device receives messages (M0, . . . , Mn) via its radio from the wireless device (S), each including an upper layer protocol data unit encapsulated within the payload of a layer 2 MAC frame without including the IPv6 header. The header insertion service inserts header information (A′) into the messages (M0, . . . , Mn) received from the wireless device (S) and retransmits the messages with complete headers as messages (M0′, . . . , Mn′). In another power-saving aspect, the relay device additionally or alternatively applies an acknowledgement detection criterion to filter out acknowledgements received from the server, and forwards the filtered out acknowledgements to the wireless device (S) via the radio at a reduced rate.

METHOD AND DEVICE TO ESTABLISH A WIRELESS SECURE LINK WHILE MAINTAINING PRIVACY AGAINST TRACKING (18225199)

Main Inventor

JOHANNES ARNOLDUS CORNELIS BERNSEN

Brief explanation

- This patent application is about a method and devices for establishing a secure wireless link between two devices.

- The method involves a pairing protocol where the first device sends identifying information over the wireless channel. - The identifying information can be used to identify the device or the user of the device. - The first device encrypts and transmits the identifying information along with random information using the public key of the second device. - The second device receives the encrypted information and uses its private key to extract the identifying information. - The devices then use a secret related to the identifying information to derive a session key. - The session key is used to establish a secure wireless link between the two devices.

Abstract

This application relates to devices and a method to establish a secure wireless link for communication between a first and a second device over a wireless physical channel, wherein a paring protocol requires sending over the wireless channel identifying information by the first device, the identifying information being data suitable for identifying the device sending the identifying information, or a user thereof, wherein the first device encrypts and transmits the identifying information and random information by using a public key information of the second device. The second device receives the encrypted identifying and random information and, using private key information associated with the public key information, it extracts the identifying information. The devices use a secret uniquely related to the identifying information to derive a session key and then use the session key to establish the secure wireless link.

Brief explanation

The patent application describes a wireless device and a relay device that communicate using a wireless communication protocol.

• The wireless device can operate in two modes:

  - In the first mode, it transmits messages with an IPv6 packet header and an upper layer protocol data unit encapsulated within the payload of a layer 2 MAC frame.
  - In the second mode, it transmits messages with only the upper layer protocol data unit encapsulated within the payload of a layer 2 MAC frame, without the IPv6 header.

• The relay device performs a header insertion service, where it receives messages from the wireless device without the IPv6 header, inserts header information into the messages, and retransmits them with complete headers.
• The relay device can also filter out acknowledgements received from the server using an acknowledgement detection criterion and forward the filtered acknowledgements to the wireless device at a reduced rate.
• The purpose of these power-saving aspects is to optimize the communication between the wireless device and the relay device while conserving energy.
