Method for associating an image-forming device, a mobile device, and a user

摘要

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.

1. A method for associating devices, the method comprising:
receiving, at a first device, user-identification information; determining whether the user-identification information is associated with a common key; in response to determining that the user-identification information is not associated with the common key, generating an optically-readable code that encodes a first set of data, wherein the first set of data includes at least first key-derivation data, a network address of the first device, and session-identification information; displaying the optically-readable code of the first set of data; establishing a connection with a second device; receiving a second set of data from the second device via the established connection, wherein the second set of data includes at least 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; determining the common key from the first key-derivation data and the second key-derivation data; encrypting, at the first device, secure-connection establishing data using the common key; sending the secure-connection establishing data from the first device to the second device via the established connection; decrypting, at the second device, the secure-connection establishing data using the common key; and establishing a secure connection using the decrypted secure-connection establishing data.
