What is WPS in Wi-Fi?

WPS: What is it?

A network security standard, Wi-Fi Protected Setup (WPS), aims to make connecting devices to Wi-Fi networks easier and more secure. It was created to remove the need for entering complicated passphrases or in-depth technical expertise when setting up a secure wireless home network for consumers.

To speed up the connecting procedure, WPS offers many device authentication options. The three main techniques that WPS uses are:

  1. Push Button (PBC): This technique entails setting up a WPS connection on the device within a certain amount of time after pushing a real or virtual button on the router. There is no need to enter a passphrase to establish the connection because the router and the device share information.
  2. Near Field Communication, or NFC: It is supported by some WPS devices. To begin the connecting procedure, users only need to touch their handset against an NFC-enabled region on the router.
  3. PIN (Personal Identification Number): The router creates a special eight-digit PIN using this technique. After that, users can connect by entering this PIN into their device. There is an alternative for individuals who would rather not utilize the push-button method.

Despite its intention to improve user ease, WPS has come under fire because of security flaws in the PIN approach. Brute-force assaults may occasionally be possible with the eight-digit PIN. Modern routers frequently come equipped with security measures like lockout times after several unsuccessful tries or the ability to completely turn off the PIN approach to ease these worries.

Users should take precautions to keep their Wi-Fi networks safe and be aware of the security capabilities available on their routers. Even while WPS is straightforward and easy to use, users should use additional secure network authentication techniques, such as WPA3 (Wi-Fi Protected Access 3), if the router supports it.

Technical Architecture

A collection of protocols and techniques make up the technical architecture of Wi-Fi Protected Setup (WPS), making connecting devices to wireless networks easier and more secure. An outline of the main elements and procedures of WPS's technological architecture is provided below:

  1. Methods of Enrollment:
    • Push Button Configuration (PBC): With this technique, the WiFi router has a virtual or real button. When turned on, devices can connect without inputting a passphrase since it starts the WPS registration process.
    • Personal Identification Number (PIN): The router is given an eight-digit PIN via WPS. To connect, users must input this PIN on their devices.
  2. Network Setup Registrar (NSR): The NSR is in charge of starting the WPS procedure. This may be accomplished by the user choosing the WPS option in the router's settings or by hitting the physical button on the router.
  3. Wi-Fi Access Point (AP) or Router: The AP or router is the hub for controlling the Wi-Fi network. Putting the required standards in place and attending to WPS enrollment requests supports WPS.
  4. Wi-Fi Client Devices: Devices trying to connect to the Wi-Fi network, such as printers, tablets, smartphones, and other Wi-Fi-capable gadgets, play an essential part in the WPS procedure. They communicate with the AP and the NSR to create a secure connection.
  5. Authentication and Key Exchange: To protect the connection between the device and the Wi-Fi network, WPS combines procedures for authentication and key exchange. This protects the network against unwanted device connections.
  6. Near Field Communication (NFC): This technology allows a more straightforward WPS procedure for supporting devices. Users may start a connection by tapping their NFC-enabled smartphone against a designated spot on the router.
  7. Security Considerations: WPS installations need to consider security issues, especially those pertaining to the PIN system. Routers sometimes provide options like lockout times after several unsuccessful PIN tries or completely turning off the PIN mechanism to increase security.

It's crucial to remember that although WPS tries to simplify Wi-Fi setup, security flaws in the PIN approach have raised some questions. To reduce possible threats, users and administrators should be aware of their routers' security features and keep them updated.

Modes of WPS:

  • PIN Method: The first step in connecting a new device is using a connection PIN that may be found on a sticker. To connect, enter this PIN on the new device or the network access point. Numerous gadgets provide universal and fundamental support for this strategy.
  • Method of Near-field Communication: The third method of connecting a new device is placing the client devices close to the access point to facilitate near-field communication. RFID and NFC tags may also be used with this technique.
  • Push Button Method: The user must press a button to join a new device using the second method. This button may be virtual on the access point or physical on the client's wireless device. Pressing this button starts an automated connection that takes a few minutes to establish. The push technique is necessary for the access point and optional for connecting devices, but the PIN method is required for every keypad and smart device.
  • USB Method: This fourth method of adding a new device uses a USB flash drive. By using the USB flash drive as a communication medium, the user can transport data between the device and the network access point using this approach.
