PW201A Wireless N Powerline AP User Guide 
6.2.2 WPA-PSK 
The  WPA  protocol  implements  the  majority  of  the  IEEE  802.11i 
standard. It  enhances  data encryption  through  the Temporal Key  Integrity 
Protocol  (TKIP)  which  is  a  128-bit  per-packet  key,  meaning  that it 
dynamically  generates  a  new  key  for  each  packet.  WPA  also  includes  a 
message  integrity  check  feature  to  prevent  data  packets  from  being 
hampered  with.  Only  authorized  network  users  can  access  the  wireless 
network. 
 
 
¾  Cipher  Type:  Select  AES  (advanced  encryption  standard)  or  TKIP 
(temporary key integrity protocol).   
¾  Security Key: Enter a security key, which must be between 8-63 ASCII 
characters long or 64 HEX characters long. 
¾  Key Renewal Interval: Specify a valid time interval for the key to be 
updated. Do not change the default value unless necessary.
