Compared with the other protocol, UDP, TCP provides
reliable communication but the communication speed is
slower.
TKIP
Abbreviation for Temporal Key Integrity Protocol. This
is used in WPA encryption standard for wireless LAN.
TKIP provides high security because it changes
encryption keys based on PSK during an on-going
communication.
UDP
Abbreviation for User Datagram Protocol. A standard
protocol used for the Internet connection. Compared
with the other protocol, TCP, UDP can transmit data
faster, but reliable communication is not guaranteed.
Unicast
Transmission of the data to the specified equipment on a
network by specifying a single address.
WPA
Abbreviation for Wi-Fi Protected Access. This is an
encryption standard for wireless LAN. It provides
higher security than the conventional WEP (Wired
Equivalent Privacy) standard. In WPA, TKIP is used for
encryption method, and PSK and EAP are used for
