Item Descriptions
SUBNET MASK
This limits the range of the IP addresses assigned to computers in order to divide the network into a
number of sections during TCP/IP connection. The value used to divide the network at this time is called
the subnet mask.
TKIP
Abbreviation for Temporal Key Integrity Protocol.
This encryption protocol provides even greater security than WEP because it changes the encryption key
at xed intervals.
WEP
Abbreviation for Wired Equivalent Privacy. This is a method for encrypting communication data. The
encryption key is created and notied only to the communicating user, so the communication data cannot
be decrypted by a third party.
WPA-EAP
WPA2-EAP
Standard for the encryption method for wireless LAN. This is an encryption method for corporations, and
encryption is performed using the external server.
WPA-PSK
WPA2-PSK
This is a standard covering encryption methods used in wireless LAN.
It provides greater security than WEP, and has functions such as a user authentication function and also
TKIP (encryption protocol) which automatically changes the encryption key at xed intervals.
And this authentication requires no authentication server.
