Which of the following protocols provides an encryption by using the Temporal Key Integrity
Protocol (TKIP)?
A.
WPA
B.
IPSec
C.
WEP
D.
EAP
Explanation:
Wi-fi Protected Access (WPA) is an interoperable security protocol for Wireless LAN (WLAN). For
using WPA, encryption is required. WPA
provides encryption by using Temporal Key Integrity Protocol (TKIP). TKIP uses a new encryption
algorithm, which is stronger than WEP
algorithm. 802.1x authentication is required in WPA.
Answer C is incorrect. Wired Equivalent Privacy (WEP) is a security protocol for wireless local area
networks (WLANs). It has two
components, authentication and encryption. It provides security, which is equivalent to wired
networks, for wireless networks. WEP encrypts
data on a wireless network by using a fixed secret key. WEP incorporates a checksum in each frame
to provide protection against the attacks
that attempt to reveal the key stream.
Answer D is incorrect. Extensible Authentication Protocol (EAP) is an authentication protocol that
provides support for a wide range of
authentication methods, such as smart cards, certificates, one-time passwords, public keys, etc. It is
an extension to Point-to-Point Protocol(PPP), which allows the application of arbitrary authentication mechanisms for the validation of a
PPP connection.
Answer B is incorrect. Internet Protocol Security (IPSec) is a method of securing data. It secures
traffic by using encryption and digital
signing. It enhances the security of data as if an IPSec packet is captured, its contents cannot be
read. IPSec also provides sender verification
that ensures the certainty of the datagram’s origin to the receiver.
