What does router wps mean?

Router wps means "Wi-Fi Security Protection Setup"; wps is the abbreviation of "Wi-Fi Protected Setup", which is a new "Wi-Fi" security launched by the "Wi-Fi" Alliance Protection settings standard for simplifying security settings and network management of "Wi-Fi" wireless, supporting PIN mode and push button mode.

What does router wps mean?

WPS in the router is the abbreviation of Wi-Fi Protected Setup, and the Chinese translation is: Wi-Fi security protection setting;

It is a new Wi-Fi security protection setting standard launched by the Wi-Fi Alliance, dedicated to simplifying the security encryption settings of wireless networks.

WPS in routers is a new Wi-Fi Security Protection Setup (Wi-Fi Protected Setup) standard launched by the Wi-Fi Alliance. The main reason for the launch of this standard is to solve the long-standing problem of wireless network encryption authentication. The disadvantage is that the setting steps are too complicated and difficult. Users often simply do not make any encryption security settings because the steps are too troublesome, thus causing many security problems.

WPS is used to simplify the security setup and network management of Wi-Fi wireless.

It supports two modes: Personal Identification Code (PIN) mode and Push Button (PBC) mode.

Working Principle

We use the metaphor of "lock and key" to describe the configuration and security mechanism of Wi-Fi Protected Setup certified products. This standard automatically uses a registry to distribute certificates to devices that are about to join the network. The user adding a new device to the WLAN can be thought of as inserting a key into a lock (i.e. starting the configuration process and entering a PIN or pressing the PBC button). At this time, Wi-Fi Protected Setup starts the information exchange process between the device and the registry, and the registry issues the authorized device and adds the network certificate (network name and security key) of the WLAN.

The new device then communicates secure data over the network without interference from intruders, which is like turning a key in a lock. Messages and network certificates are securely exchanged over the air using the Extensible Authentication Protocol (EAP), one of the authentication protocols used by WPA2. At this time, the system will start the handshake exchange process, the devices will complete mutual authentication, and the client device will be connected to the network. The registry activates the security mechanism by transmitting the network name (SSID) and WPA2 "pre-shared key" (PSK). Since the network name and PSK are automatically distributed by the system, the certificate exchange process requires almost no user intervention. The "lock" of WLAN security settings is easily opened.

Advantages of WPS

WPS can automatically configure the network name (SSID) WPS and WPA security key. When connecting a WPS device, users do not need to understand concepts such as SSID and security keys. A user's security key cannot be cracked by outsiders because it is randomly generated. Users do not have to enter pre-known password segments or lengthy hexadecimal strings. Messages and network certificates are securely exchanged over the air using the Extensible Authentication Protocol (EAP), one of the authentication protocols used by WPA2. WPS supports Windows Vista operating system.

Disadvantages of WPS

WPS does not support "ad hoc" networks where devices communicate directly without relying on APs. All Wi-Fi devices in the network must be WPS certified or compatible with WPS. Otherwise, WPS cannot be used to simplify network security configuration. Since the hexadecimal strings in WPS are randomly generated, it is difficult to add a non-WPS client device to the WPS network. WPS is a new authentication technology, so not all manufacturers support it.
