1. A communication apparatus comprising:
one or more antennas;
one or more processors; and
one or more memories including instructions that, when executed by the one or more processors, cause the communication apparatus to:
acquire information regarding a public key of a first communication apparatus;
transmit a request signal to the first communication apparatus to execute authentication processing, the request signal including authentication information derived by calculating a hash value of the public key included in the acquired information, wherein the request signal and the authentication information do not include the public key itself included in the acquired information,
wherein the authentication processing is executed by the first communication apparatus which has received the request signal, wherein, in the authentication processing, authentication is determined to be successful in a case where second authentication information which has been calculated based on the public key of the first communication apparatus and is stored in the first communication apparatus and the authentication information included in the request signal conform to each other, and wherein the first communication apparatus which has determined that the authentication has succeeded transmits, to the communication apparatus, an authentication response signal indicating the success of the authentication, and
provide, in a case where a setting request signal at least including information indicating that the first communication apparatus wishes to obtain a role of a device to provide other devices with a communication parameter is received from the first communication apparatus, the setting request signal being transmitted from the first communication apparatus to the communication apparatus at least after the authentication processing is successful, the first communication apparatus with a first parameter, wherein the first communication apparatus operates, based on the first parameter, as a device to provide a second device with a communication parameter for connection to a wireless network, and
wherein the request signal is a signal that is wirelessly transmitted via the one or more antennas of the communication apparatus and that is wirelessly transmitted by the communication apparatus via no other apparatus and expected to be received by the first communication apparatus.
