Wi-Fi Protected Access: A Secure Communication Protocol

This presentation provides an overview of Wi-Fi Protected Access (WPA), a security protocol for creating a secured wireless network. It explains how WPA works, its advantages and disadvantages, and its comparison to other security technologies. The presentation also discusses the future of WPA and its applications in wired and wireless communications.

Introduction
• The Wi-fi Protected Access is mainly the security standard that is set
for handling the users of computing the devices. (Au, 2016)
• It is mainly equipped with a proper wireless internet connection that is
mainly to improve the security standards and the sophisticated data
encryption.

Objective
WPA: WPA is mainly for handling the message integrity
check, with extended initialisation vector and re-keying
mechanism.
How does it work: It works on the Remote
Authentication Dial in User Service with access to the
device credentials so that the users can be
authenticated before they are connected to the network.
Where is it used: configuring security on home
networks, office etc.
Pros & Cons: It provides a better and stronger user
authentication like RADIUS to authenticate the user. The

What is WPA
•It is a security protocol which has been for creating a
secured wireless network.
•They tend to offer the improvement with handling
security keys and working on the systems on the
beginning and end of data transfer. (Linkola et al.,
2016).
•The standards are set for using the temporal key
integrity protocol that prevents the intruders from
creating own encryption key to match by secured
network.

How WPA Works
1. WPA works with
connecting to the
wireless network
where the design is
based on firmware
upgrade. (Dahiya et
al., 2016).
2. It allows a strong user
authentication which
depends on
operations for all the
users.
3. The password will
trigger the

What forms of communication is it
used in
•It is used in Wi-Fi Wireless Communication
•Extensible Authentication Protocol (EAP)
•wired communications
•Routers, web servers, and BSs.
•Prepaid telephone services
•Email
•Interactive chat, communication
•Games

Advantages of WPA
a. It is simple to use
b. A proper mobility is also ensured.
c. The personalized forms.
d. Easy to carry and handle. (Zhan et al., 2016)
e. The increased sales have made it more demanding
for the people.
f. Time saving as well.

Disadvantages of WPA
a. It tends to consume more of battery life.
b. There are very small screens for the display and here
the speed of access is also a major disadvantage.
c. There are issues related to the pricing and availability
d. A major lack is in the user habit (Dahiya et al., 2016).
e. less memory.

Comparison to other security
technologies
a. Wired Equivalent Privacy: It works on 802.11 with
handling the easy hacking due to the 24 bit initiation
vector and weak authentication. Less used.
b. WPA (Wi-Fi Protected Access): It includes the
standards to address the major flaws of WEP where
the personal and enterprise is covered in this.
c. WPA2: It woks on the current standards and new
hardware.

The future of WPA
a. It has been effective for Advanced Encryption
Standard AES encryption is set with the Cipher Block
Chaining Message Authentication Code Protocol (CCMP)
in Counter Mode.
b. The CCMP tends to generate a message with the
integrity code with non-repudiation and integrity.
c. It also offers a higher level of security with stronger
encryption with creation of unique session keys on every
association to the client.

Conclusions
•WAP works on authentication and key distribution with
home users and small business. (Au et al., 2016).
•The 4-way handshake helps in authenticating the client
access point, establishing and installing the TKIP
encryption keys.
