Communication apparatus and communication parameter configuration method thereof

摘要

A communication apparatus functioning as a master device denies participation by new communication apparatuses in a network in communication parameter configuration mode based on participation statuses of communication apparatuses functioning as slave devices in the network. The communication apparatus functioning as a master device establishes the network in communication parameter configuration mode between the communication apparatuses participating in the network, and configures communication parameters.

主权项

1. A communication device, comprising:
a determination unit configured to determine whether the communication device itself becomes a providing apparatus for providing communication parameters for performing wireless communication compliant with IEEE 802.11 standard series, wherein the communication parameters include information of an SSID (Service Set Identifier) and an encryption method; a first generation unit configured to generate a first random number for generating an encryption key for encrypting the communication parameters; an obtaining unit configured to obtain information of a second random number generated by an other communication device; a second generation unit configured to generate an encryption key for encrypting the communication parameters based on the first random number generated by the first generation unit and on the information on the second random number that is generated by said the other communication device and is obtained by the obtaining unit; a transmission unit configured to transmit, to the other communication device, the communication parameters, which has been encrypted based on the encryption key generated by the second generation unit, in a case where the determination unit determines that the communication device itself becomes the providing apparatus; and a communication unit configured to perform, with the other communication device, wireless communication complaint with IEEE 802.11 standard series using the communication parameters.
