- the storage unit 306 is a storage device that can be composed of a ROM and a RAM that store programs and data that the AP operates.
- Fig. 4 shows RSNE (Robust Security Network element) defined by IEEE802.11.
- the RSNE is stored in a management frame conforming to IEEE802.11.
- the Element ID field 401 indicates that the element is an RSNE. That is, the value becomes 48.
- the Pairwise Cipher Suite Count field 405 indicates the number of corresponding encryption methods. Specific values are shown in the Pairwise Cipher Suite List field 406 . For example, 00-0F-AC-04 corresponds to CCMP-128. If the Pairwise Cipher Suite Count field 405 indicates that a plurality is supported, for example, if the Pairwise Cipher Suite Count field 405 is set to 2, a plurality of 406 are made consecutive. For example, when supporting CCMP-128 and GCMP-128, 00-0F-AC-04 is followed by 00-0F-AC-08. This order may be reversed. Any number of corresponding numbers may be used.
- the AKM Suite Count field 407 indicates the number of corresponding authentication methods. Specific values are shown in the AKM Suite List field 408. In this embodiment, since only WPA3-SAE is assigned to RSNE, the AKM Suite Count field 407 is set to 1, and the AKM Suite List field 408 is set to 00-0F-AC-08 indicating SAE. Note that this value may be a value specified in WPA3 or later. In other words, when an authentication method with SHA-384 as hash in SAE is added to 00-0F-AC-14, it may be indicated in addition to the above. Also, 00-0F-AC-09 that implements FT (Fast Transition) in SAE may be included. However, 00-0F-AC-02 and 00-0F-AC-06 indicating PSK are not included because only WPA3 corresponds to FT implementation in SAE.
- Fig. 5 shows the Extended Capabilities defined in IEEE802.11. Extended Capabilities are stored in a management frame conforming to IEEE802.11.
- Element ID field 501 Element ID field 501
- Length field 502 Element ID field 501
- Extended Capabilities field 503 Element ID field 501
- the field 503 includes an SAE Password Identifiers In Use subfield 504 and an SAE Password Identifiers Used Exclusively subfield 505 . These fields are enabled when using a Password ID that can set an ID for changing the password for each user when building a network with the same SSID. For example, if a part of the constructed network has a Password ID, the SAE Password Identifiers In Use subfield 504 is enabled. If all constructed networks have a Password ID, subfields 504 and 505 are validated.
- the values stored in the subfields in the Extended Capabilities field 503 may be valid, for example, when building a network for Multi-Link communication in addition to an existing network. For example, when connecting to a network for Multi-Link communication, by making a Password ID mandatory, it is possible to force a connection using an authentication method corresponding to the Password ID. In order to make Passowrd ID mandatory, for example, it is conceivable to prepare a bit that must be connected by a predetermined method for compatible devices, and to set that bit.
- the SAE Password Identifiers In Use subfield 504 may always be enabled. It is conceivable that security will be improved by using the Password ID, as the confidentiality of the password will be enhanced. Therefore, by enabling Password ID whenever using Multi-Link communication, the AP can build a more secure network. Conversely, the STA can also control an AP that builds a network for Multi-Link communication as unreliable and not connect to it, even though SAE Password Identifiers In Use is disabled. Also, for the AP, when a connection request is made by a STA that does not support Password ID, the STA may be regarded as untrustworthy and may be controlled not to connect.
- Fig. 6 shows RSNXE (RSN Extension element) defined by IEEE802.11.
- RSNXE is stored in a management frame conforming to IEEE802.11.
- Element ID field 601 Length field 602, and Extended RSN Capabilities field 603 from the beginning.
- the SAE hash-to-element subfield 606 indicates that the H2E (Hash to Element) method is supported among the SAE authentication specified by WPA3.
- the SAE-PK subfield 607 indicates that the SAE authentication corresponds to the SAE-PK (SAE Public Key) method.
- SAE hash-to-element is one of the SAE authentication methods, and it is possible to pre-calculate the parameters to be exchanged offline. This makes it possible to prevent side-channel attacks in which a calculated value is estimated based on the calculation time, thereby enhancing security.
- the SAE hash-to-element subfield 606 or SAE-PK subfield 607 may be enabled.
- SAE hash-to-element whenever Multi-Link is used, it is possible to perform communication built on a network with higher security.
- the communication device 102 can determine that the APs constructing the multi-link network are unreliable and should not be connected.
- the AP can determine that the STA is unreliable and will not connect.
- SAE-PK is one of the authentication methods of SAE, and it is a method that can confirm whether the STA is trying to connect to a legitimate AP. If the AP with which the STA is trying to establish a connection is a fake AP, the STA can determine that it is a fake AP by verifying the value. This can contribute to improving security in public wireless LANs. Therefore, by enabling SAE-PK whenever Multi-Link communication is used, the communication device 102 can construct a network with higher security. Conversely, even though the SAE-PK is invalid, the STA can determine that the AP that constructs the network for Multi-Link communication is unreliable and will not be connected. Furthermore, when an STA that does not support SAE-PK connects to the AP, it can be determined that the STA is unreliable and will not be connected.
- WPA3 is selected when Multi-Link communication is selected by the control unit 202 executing the program stored in the storage unit 201 of the communication device 101.
- the flow of processing for controlling to Multi-Link communication is a technology under study in the IEEE802.11be standard, and communication devices capable of executing Multi-Link communication are likely to support WPA3. Therefore, when multi-link communication is performed, authentication is performed using WPA3, which allows authentication to be performed more safely. It is assumed that the communication device 101 has at least a wireless LAN control unit capable of Multi-Link communication.
- This flowchart is started when the communication device 101 constructs the network or when the user instructs to change the network settings.
- the communication device 101 displays a wireless setting screen to the user (S701). The details of the screen displayed at this time will be described later.
- a method of determining whether or not Multi-Link communication is selected in S702 will be described later with reference to display examples shown in FIGS. If it is determined in S702 that the Multi-Link communication has been selected, it is checked whether or not there is an STA that has already established a connection with the communication apparatus 101 via a single Link (S703).
