WPA使用802.1X认证服务器给每个用户分配不同的密钥. 但是它在安全性比较差的 "预先共享密钥 (PSK)" 模式中也有效. PSK用于家庭和小型办公室网络,每个用户都有同样的密码口令. WPA-PSK 也叫做 WPA-Personal(WPA个人). WPA-PSK使用TKIP或AES加密方法把Brother无线设备和接入点联系起来.WPA2-PSK使用AES加密方法把Brother无线设备和接入点联系起来.
TKIP是 Temporal Key Integrity Protocol(临时密钥完整性协议)的简称,是一种加密方法.TKIP提供结合信息完整性检查和重新按键机制的信息包密钥.
AES是Advanced Encryption Standard(高级加密标准)的简称,是 Wi-Fi® 授权的高效加密标准.
WPA-PSK/WPA2-PSK和TKIP或AES使用预先共享密钥 (PSK),字符长度大于8并且小于6
