Wi-Fi Protected Setup

Wi-Fi Protected Setup は、一般家庭および小規模オフィス環境でセキュリティに守られたWi-Fi ネットワークの簡単・手軽な設定をサポートできるように考えられたテクノロジを基盤にした、オプションの認定プログラムです。 Wi-Fi Protected Setupでは、ネットワークの構成設定とセキュリティの設定についてほとんどのユーザーが使い慣れている手法 (プッシュボタン、PIN (暗証番号) 入力、NFCによる接続の3種類) をサポートしています。

他のすべてのWi-Fi CERTIFIED製品と同様に、Wi-Fi Protected Setup 製品も業界標準となっているWPA2のセキュリティ機能によって保護されています。Wi-Fi Protected Setup によって、消費者はセキュリティ保護されたWi-Fi 接続をデバイス間やネットワーク構成内で、簡単・手軽に設定できます。Wi-Fi Protected Setup ネットワークには、後からデバイスを簡単に追加していくことができます。

Wi-Fi 接続をサポートするデバイスの数と幅が広がるのに伴い、ネットワーク構成およびセキュリティ設定へのよりシンプルで標準化されたアプローチの重要性も高まっています。Wi-Fi Protected Setupによって、Wi-Fi ユーザーは多様な製品のタイプやブランドなどを気にすることなく自由に製品を選び、自分のネットワークへ簡単に追加することが可能になります。

Frequently Asked Questions
  • Are Wi-Fi CERTIFIED products protected by security?

    Yes. All Wi-Fi CERTIFIED products are tested for WPA2 or WPA3. The only way to be sure that a product meets the latest security standards is to purchase only Wi-Fi CERTIFIED products.

     

  • How does Wi-Fi Alliance help ensure product compatibility and a good user experience for certified products?

    Compatibility and quality are achieved through rigorous testing of Wi-Fi products. Consumers should always look for the Wi-Fi CERTIFIED logo to ensure the best user experience possible.

     

  • How do companies use the Wi-Fi Protected Setup trademark?

    The term “Wi-Fi CERTIFIED Wi-Fi Protected Setup™” designates products that have been certified by Wi-Fi Alliance, and is the commercial name for the certification program. The underlying specification or technology is called “Wi-Fi Simple Configuration Technical Specification”. Only products which have completed and passed Wi-Fi certification to the Wi-Fi Simple Configuration test plan may use the Wi-Fi Protected Setup name. On second instance, you may refer to “Wi-Fi Protected Setup “products (dropping the term Wi-Fi CERTIFIED).

  • How does Wi-Fi Protected Setup work?

    There are three primary approaches to network setup within Wi-Fi Protected Setup: push-button, PIN entry, and Near Field Communication (NFC). PIN entry is mandatory in all Wi-Fi Protected Setup devices, while push-button and NFC are optional and may also be found in some devices.

    Push-button configuration (PBC): in some Wi-Fi Protected Setup networks, the user may connect multiple devices to the network and enable data encryption by pushing a button. The access point/wireless router will have a physical button, and other devices may have a physical or software-based button. Users should be aware that during the two-minute setup period which follows the push of the button, unintended devices could join the network if they are in range.

    PIN entry: in all Wi-Fi Protected Setup networks, a unique PIN (Personal Identification Number) will be required for each device to join the network.  A fixed PIN label or sticker may be placed on a device, or a dynamic PIN can be generated and shown on the device's display (e.g., a TV screen or monitor).  PIN is used to make sure the intended device is added to the network being set up and will help to avoid accidental or malicious attempts to add unintended devices to the network.

    A registrar device (which could be an Access Point/wireless router, PC television, or other device) will detect when a new Wi-Fi device is in range, and prompt the user to enter the PIN, if he or she wishes to add the new device to the network.  In this mode, Wi-Fi Protected Setup network encrypts data and authenticates each device on the network.  The PIN entry method is supported in all devices.

    Near Field Communication (NFC):  A Near Field Communication interface can be used to transfer network settings to a new device without requiring manual entry of its PIN.  The NFC method provides strong protection against adding an unintended device to the network. This is an optional method for Wi-Fi Protected Setup Access Points and devices.
