Key agreement - H04W 12/069: using certificates or pre-shared keys - H04W 12/35: {Protecting application or service provisioning, e.g. securing SIM application provisioning} - H04W 84/12: WLAN [Wireless Local Area Networks] - H04W: WIRELESS COMMUNICATION NETWORKS (broadcast communication H04H; communication systems using wireless links for non-selective communication, e.g. wireless extensions H04M1/72) ## Abstract In a case where a predetermined operation is received from a user, if a signal compliant with the DPP standard is received, a communication parameter sharing process is executed by a method compliant with the DPP standard, whereas if a signal compliant with another standard is received, the communication parameter sharing process is executed by a method compliant with the other standard. ## Claims ### Claim 1 A communication apparatus comprising: a reception unit configured to receive a predetermined operation from a user; a first processing unit configured to execute a process of sharing a communication parameter for connecting to a wireless network with a first another communication apparatus in accordance with a first method compliant with a Wi-Fi Device Provisioning Protocol (DPP) standard; a second processing unit configured to execute a process of sharing a communication parameter for connecting to the wireless network with a second another communication apparatus in accordance with a second method compliant with another standard different from the DPP standard; and a control unit configured to control execution of the processes of sharing so that, in a case where the reception unit receives the predetermined operation, the process of sharing by the first processing unit is executed in a case where a first signal compliant with the DPP standard is received, and the process of sharing by the second processing unit is executed in a case where a second signal compliant with the other standard is received. ### Claim 2 (depends on 1) The communication apparatus according to claim 1, wherein the first signal is a signal that is used between the communication apparatus and the first other communication apparatus to share a predetermined public key defined in the DPP standard with the first other communication apparatus using an authentication code. ### Claim 3 (depends on 2) The communication apparatus according to claim 2, wherein the predetermined public key is a bootstrapping key compliant with the DPP standard. ### Claim 4 (depends on 1) The communication apparatus according to claim 1, further comprising an input unit configured to prompt the user to input a code, wherein the first processing unit and the second processing unit execute the process of sharing using a common code input via the input unit. ### Claim 5 (depends on 1) The communication apparatus according to claim 1, wherein the other standard is a Wi-Fi Protected Setup (WPS) standard, and wherein the other standard is a method in accordance with a personal identification number (PIN) method compliant with the WPS standard. ### Claim 6 (depends on 1) The communication apparatus according to claim 1, wherein the other standard is a Wi-Fi Protected Setup (WPS) standard. ### Claim 7 (depends on 6) The communication apparatus according to claim 6, wherein the second method is a method in accordance with a push button configuration (PBC) method compliant with the WPS standard. ### Claim 8 (depends on 6) The communication apparatus according to claim 6, wherein the other standard is a method in accordance with a personal identification number (PIN) method compliant with the WPS standard. ### Claim 9 (depends on 1) The communication apparatus according to claim 1, wherein the other standard is a Wi-Fi Direct standard. ### Claim 10 (depends on 1) The communication apparatus according to claim 1, wherein the other standard is an AirStation One-Touch Secure System (AOSS) standard. ### Claim 11 (depends on 1) The communication apparatus according to claim 1, further comprising a setting unit configured to set which standard is to be used as the other standard. ### Claim 12 (depends on 1) The communication apparatus according to claim 1, wherein the reception unit is a button. ### Claim 13 A method for controlling a communication apparatus, the method comprising: receiving a predetermined operation from a user; executing a first process of sharing a communication parameter for connecting to a wireless network with a first another communication apparatus in accordance with a first method compliant with a Wi-Fi Device Provisioning Protocol (DPP) standard; executing a second process of sharing a communication parameter for connecting to the wireless network with a second another communication apparatus in accordance with a second method compliant with another standard different from the DPP standard; and controlling execution of the processes of sharing so that, in a case where the predetermined operation is received, the first process of sharing is executed in a case where a first signal compliant with the DPP standard is received, and the second process of sharing is executed in a case where a second signal compliant with the other standard is received. ### Claim 14 A storage medium storing a program for causing a computer to function as a communication apparatus that performs a process comprising: receiving a predetermined operation from a user; executing a first process of sharing a communication parameter for connecting to a wireless network with a first another communication apparatus in accordance with a first method compliant with a Wi-Fi Device Provisioning Protocol (DPP) standard; executing a second process of sharing a communication parameter for connecting to the wireless network with a second another communication apparatus in accordance with a second method compliant with another standard different from the DPP standard; and controlling execution of the processes of sharing so that, in a case where the predetermined operation is received, the first process of sharing is executed in a case where a first signal compliant with the DPP standard is received, and the second process of sharing is executed in a case where a second signal compliant with the other standard is received.
