WPS以及它的兩種方式PIN與PBC的理解
WPS - Wi-Fi Protected Setup PBC - Push ButtonConfiguration 這個是不需要密碼的方式 PIN - Personal Information Number 這個是要用密碼的方式通常用在電子裝置的互通,例如和電視機啥的
WPS分為PBC(BUTTON)和PIN兩種方式:
A PBC: 按WPS按鈕實現WPS安全連線.
- 在AP中,在WPS設定中,設定為啟用.
- 按一下客戶端(無線網絡卡)上的WPS按鍵,搜尋WPS網路.
- 按一下AP上的WPS按鍵,WPS開始連結協商,片刻後WPS安全連線成功建立.
B PIN
B1)PIN(Internal Registra,
- 在WPS設定中,把狀態設定為啟用.
- 開啟客戶端WPS設定軟體,選擇在路由器中輸入PIN的方式連線,同時軟體上還會顯示客戶端當前的PIN碼.
- 開啟路由器介面,在WPS模式裡選擇PIN模式,然後輸入客戶端的PIN碼, 點新增新裝置,一會兒後,WPS安全連線成功建立.
B2)PIN(External Registra,
- 在AP中,在WPS設定中,設定為啟用.
- 記住AP的PIN碼,然後開啟客戶端(無線網絡卡)WPS設定軟體,選擇以AP的PIN碼來進行連線.
- 輸入完PIN碼後,點下一步,一會兒後,WPS安全連線成功建立.
WPS(Wi-Fi Protected Setup,Wi-Fi保護設定),它是由Wi-Fi
不過現在有了WPS,這些問題就不再是問題啦。我們只需按一下無線路由器上的WPS鍵,就能輕鬆快速地加密無線網路的傳輸資料,從而阻止非法使用者的入侵。一個小小的“WPS”鍵既保證了無線網路的安全,又讓我們設定加密的步驟變得極其簡易,所有使用者都能輕鬆上手。
WPS的優點
WPS可以自動配置網路名(SSID)及WPA安全金鑰,對於普通使用者來說,無需瞭解SSID和安全金鑰的概念就能實現安全連線;而且使用者的安全金鑰不可能被外人破解,因為它是隨機產生的;最重要的是使用者無需記憶冗長的密碼,省去了忘記密碼的麻煩。
WPS的缺點
使用WPS簡化網路安全配置的最基本要求就是,接入點和客戶端裝置均須通過WPS認證,如果一方沒有通過認證,均無法實現WPS功能。而且由於各個廠商間的差異,不同品牌的接入點和客戶端也會出現相容性的問題,因此建議大家選擇同一品牌的產品。
WPS的兩種實現方式:
目前通過WPS認證的產品能夠為使用者提供兩種實現方式,即按鈕配置(Push Button Configuration,PBC)和輸入PIN碼(Pin InputConfiguration,PIN)。
Wi-Fi Protected Setup (WPS)
Wi-Fi Protected Setup (WPS) is a latest standard published bythe Wi-Fi Alliance with the aim of simplifying the configuration process toestablish a secure wireless home network. Previously, users need to manuallysetup a Wireless Network Name (SSID) and assign a passphrase as anencryption to secure their wireless network. This can not be done without anextensive knowledge in wireless networking.
WithWPS, the entire configuration process will be automatically configured with twomethods:
1. Push Button Configuration (PBC), in which the user simply has to push abutton, either an actual or virtual one, on both WPS device.
2. PersonalInformation Number (PIN), inwhich a PIN is taken from a sticker or a display and entered into the AccessPoint (AP) or other WPS devices to connect.
Advantages of WPS
1. WPSautomatically configures the wireless network.
2. There is no need to know the SSID and passphrase to connect to thewireless network.
3. The key is randomly generated and less predictable minimizing the riskof network intrusion.
4. Eliminates the need to enter complicated hexadecimal passphrase.
5. WPS introduce Extensible Authentication Protocol (EAP) in WPA2encryption that allows secure transmission of sensitive information.
Disadvantages of WPS
1. Deviceswithout WPS certification is not able to take advantage of the enhancedsecurity provided by WPS.
2. Non WPS devices will require the user to enter the long hexadecimalpassphrase manually.
3. WPS does not supports "Ad Hoc" connection that allows devicesto communicate directly with each other. All connections must go through theAP.
4. Not all devices support WPS as the technology is still new.
