Enhanced 4-way Handshake Process in IEEE802.11i with Cookies
In today's fast online information processing era, it is mandatory to deal with the security issues in the computer networks. Wi-Fi Protected Access (WPA), IEEE802.11i, Data Encryption Standard (DES), Advanced Encryption Standard (AES) are used to achieve better security. The paper deals to explain and avoid the two types of attacks, Denial of Service (DoS) and Memory Exhaustion (ME), generated during the 4-way handshake process used for connection establishment over IEEE802.11i. Some amendments in 4-way handshake process are made to reduce these types of attacks.
