WPA3 (Wi-Fi Protected Access 3) is the next generation of Wi-Fi security, designed to enhance protection over WPA2 by introducing features like stronger encryption and better defense against attacks such as KRACK and man-in-the-middle. WPA2, adopted in 2004, provided data protection but had vulnerabilities that WPA3 addresses, including improved password protection and simplifying Wi-Fi connection processes. The document outlines the evolution of wireless security protocols and discusses the limitations of previous systems while highlighting the advantages of adopting WPA3.

3. Introduction
 “WPA” stands for Wi-Fi Protected
Access.
 WPA 3 is the next generation of wi-fi
security.
 It is standard version of WPA2.
 WPA3 will add new features to simplify
Wi-Fi security.

4. List of Wireless Security
Protocols
WEP(Wired Equivalent Privacy)
WPA(Wi-Fi Protected Access).
WPA2(Wi-Fi Protected Access I

5. WEP(Wired Equivalent
Privacy
 It was developed in 1997.
 part of the IEEE 802.11
 It use 64bit encryption.
 It uses the RC4 encryption protocol to secure
the data.
 specification ƒgoal :
make the WiFi network at least as secure as a
wired LAN (that has no particular protection
mechanisms)

7. WPA(Wi-Fi Protected Access
Developed by the Wi-Fi Alliance to secure
wireless computer networks
• It was adopted in 2003 to solve weakness in
WEP
• Standardized in IEEE 802.11i
• Increased in safety: encryption 128 bits
• Known as TKIP(Temporal key Integrity)
• It uses RC4 encryption to secure the data
• It uses the MIC and frame counter to verify
the integrity of the data.

code)

9. WPA Vulnerabilities
 Weakness in the key
combination algorithm
 PSK is vulnerable to
eavesdropping and
dictionary attack.
 TKIP vulnerability allows
attacker to guess IP
address of the subnet.

10. WPA2
 WPA2 is the security method
added for wireless networks that
provides stronger data protection and
network access control.
 Has replaced WPA.
 Was adopted in 2004.
 WPA2 has two types : WPA2-
Personnal,WPA-Enterprise.

11. WPA 2 Encryption
 WPA2 uses AES with a key length of
128 bit to encrypt data.

12. Limitation of WPA2
 The Password can be cracked online.
 Anyone can disconnect you.
 Once anyone know the password he
can spoof or sniff the wifi users by
“Man in the middle attack”.
 A hacker can hack the whole wifi
network and its user by using
“KRACK”.

13. What is Man in the middle attack
?
Man in the middle attack is a attack where
attacker secretly steal the data and
information of victim which is sending to
the web servers.

14. KRACK (Key Reinstallation
Attack)
•KRACK ("Key Reinstallation Attack") is a severe replay
attack (a type of exploitable flaw) on the Wi-Fi Protected
Access protocol that secures Wi-Fi connections
•It was discovered in 2016
•It was discovered by Belgian researchers Mathy Vanhoef and
Frank Piessens.

15. Tools
 Here are the some tools that bypass
wireless securities :

16. Advantages of WPA3
 Password protection.
 Protection against KRACK and Man in
the middle attack.
 It will simplify to connect with wifi.
 Stronger encryption.
 Protect public Wi-Fi.

17. Summary
 1.WPA2 is the improved version of
WPA.
 2.WPA only supports TKIP encryption
while WPA2 supports AES.
 3.WPA2 requires more processing
power than WPA
