Abstract
Systems, methods, and devices for associating an image forming device and a mobile device receive, at a first device, a request to establish a connection with a second device; generating an optically-readable code that encodes a first set of data, wherein the first set of data includes first key-derivation data; display the optically-readable code of the first set of data; establish a communication channel with the second device; receiving a second set of data from the second device via the established communication channel, wherein the second set of data includes second key-derivation data, and wherein the second key-derivation data is generated in response to receiving the first key-derivation data at the second device; and determine the common key from the first key-derivation data and the second key-derivation data.
