    Abstract: Embodiments for device pairing using optical codes are described. One embodiment is a wearable device with an image sensor configured to capture an image including a first optical code from a first host device. The wearable device decodes the first optical code, and in response to the first optical code, initiates broadcast of a pairing advertisement. The host device displays a second optical code in response to the pairing advertisement, and the wearable device captures and processes the second optical code to determine a host pairing advertisement code. The wearable device then, in response to the second optical code, initiate broadcast of a second pairing advertisement including the host pairing advertisement code. In various embodiments, a secure wireless channel is then established and used for further secure communications.

    Abstract: Embodiments for device pairing using optical codes are described. One embodiment is a host device with a memory and one or more processors configured to pair the host device with a wearable device. The paring involves generating and displaying an image including a first optical code, decoding decode a pairing advertisement from the wearable device, generating a second optical code, the second optical code comprising a host pairing advertisement code, and decoding a second pairing advertisement including the host pairing advertisement code. Additional embodiments involve, in response to the second pairing advertisement, establishing a communication channel between the host device and the wearable device, communicating keys between the host and wearable device, and using an application-level elliptic curve Diffie-Hellman (ECDH) exchange with the first key and the second key to establish a shared secret.

    Abstract: Systems and methods for device handshaking are described. Embodiments for client device and associated wearable device initiated handshaking are described. In certain embodiments, a device such as wearable camera eyeglasses having both high-speed wireless circuitry and low-power wireless circuitry communicates with a client device. The low-power wireless circuitry is used for signaling and to manage power on handshaking for the high-speed circuitry in order to reduce power consumption. An analysis of a high-speed connection status may be performed by a client device, and used to conserve power at the glasses with signaling from the client device to indicate when the high-speed circuitry of the glasses should be powered on.
