Wi-Fi Protected Access (WPA) (Wireless Protected Access), Wi-Fi Protected Access 2 (WPA2), and Wi-Fi Protected Access 3 (WPA3) are the three security certification programs developed after 2000 by the Wi-Fi Alliance to secure wireless computer networks.

WPA （英語： Wi-Fi Protected Access），意即「Wi-Fi存取保護」，是一種由Wi-Fi聯盟制訂與發佈，用來保護 無線網路 （Wi-Fi）存取安全的技術標準。 前一代 有線等效加密 （Wired Equivalent Privacy, WEP）系統中，被發現若干嚴重的弱點，因此Wi-Fi聯盟推出WPA、WPA2與WPA3系列來加強無線網路安全。 目前廣泛實作的有WPA、WPA2兩個標準。 第一代WPA (以TKIP為基礎)由2003年開始啟用，WPA實作了 IEEE 802.11i 標準的大部分，是在802.11i完備之前替代WEP …

2022年12月6日 · As the most up-to-date wireless encryption protocol, WPA3 is the most secure choice. Some wireless APs do not support WPA3, however. In that case, the next best option is WPA2, which is widely deployed in the enterprise space today.

2024年4月29日 · 通过采用WPA，用户可以放心地在无线网络上进行在线交易、传输敏感信息和访问个人账户，而不必担心数据泄露和攻击风险。对于企业来说，WPA也是确保网络安全和保护商业机密的关键工具。 WPA2. WPA2是一种无线安全协议，是WPA（Wi-Fi Protected Access）协议的 …

2025年1月29日 · To address the inadequacies of WEP, the Wi-Fi Alliance introduced Wi-Fi Protected Access (WPA) in 2003. WPA implemented several new features intended to enhance wireless security. How WPA Works. WPA introduced the Temporal Key Integrity Protocol (TKIP), which dynamically changes the encryption keys as the system operates.

2024年6月28日 · Wired Equivalent Privacy (WEP) is an early security protocol for wireless networks. Introduced in 1997, WEP was designed to provide a level of security comparable to wired networks by encrypting data sent over Wi-Fi. It uses a static key to encrypt data, which is shared between devices and the wireless router.

WPA全名为Wi-Fi Protected Access，有WPA、WPA2和WPA3三个标准，是一种保护无线电脑网络（Wi-Fi）安全的系统，它是应研究者在前一代的系统有线等效加密（WEP）中找到的几个严重的弱点而产生的。

2025年2月3日 · Wi-Fi Protected Access is a Wi-Fi security technology developed in response to the weaknesses of Wired Equivalent Privacy standards. It improves upon WEP's authentication and encryption features. WPA2 and WPA3 are upgraded forms of WPA; since 2020, every Wi-Fi-certified product must use WPA3.

Wi-Fi Protected Access (WPA) is a security standard for computing devices equipped with wireless internet connections. WPA was developed by the Wi-Fi Alliance to provide more sophisticated data encryption and better user authentication than Wired Equivalent Privacy (WEP), the original Wi-Fi security standard. WPA was initially released in 2003.

WiFi routers support a variety of security protocols to secure wireless networks: WEP, WPA and WPA2. However WPA2 is recommended over its predecessor WPA (Wi-Fi Protected Access). Probably the only downside of WPA2 is how much processing power it …
