Communication apparatus, control method thereof, and storage medium

摘要

A first communication apparatus that functions as a providing apparatus that provides an encryption key or as a receiving apparatus that receives an encryption key provided by a providing apparatus, and that performs a key sharing process for sharing an encryption key with another apparatus, confirms whether or not the first communication apparatus functioned as the providing apparatus in the key sharing process performed among a plurality of apparatuses present on a network in which the first communication apparatus is joining; compares identification information of a second communication apparatus that has newly joined the network with identification information of the first communication apparatus; and determines whether or not the first communication apparatus is to function as a providing apparatus in the key sharing process performed between the first and the second communication apparatuses based on the result of the confirmation and the comparison.

主权项

1. A communication apparatus, comprising:
a determination unit configured to determine whether to act as an authenticating apparatus that authenticates, for performing wireless communication in a wireless network, an authenticated apparatus or as an authenticated apparatus that is authenticated by an authenticating apparatus; an authentication unit configured to authenticate, in a case where the determination unit determines that the communication apparatus acts as the authenticating apparatus, a first other communication apparatus; and a sending unit configured to send, in a case where a search request is received from a second other communication apparatus that does not participate in a communication group while the communication apparatus and the first other communication apparatus form the communication group, information indicating the first other communication apparatus that the communication apparatus authenticated while acting as the authenticating apparatus, to the second other communication apparatus.
