Abstract:
Wireless Computer Network is most dominant network for information transmission in modern age. Today due to lack of network security various threats propagate in network. Therefore, security of wireless computer network is big issue,to remove these threats various security algorithms such as Data
Encryption Standard (DES), Advanced Data Encryption (AES), Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), IEEE802.11i used for achieve enhanced security in wireless network. Wireless network can be protectedif security principles can be bounded with these algorithms. Authentication one of security principlecan be achieved by Three Way Handshake approach, 4-way handshake approach etc. respectively. 4-way handshake approach introduces by many researchers but this approach has some inadequacy eg. Denial of Service (DoS), Memory Exhaustion (ME), Distributed Denial of Service (DDoS), Flooding attacks. These attacks in authentication process make him as unsecure authentication algorithm. Due to exploiting the vulnerabilities in 4-way handshake approach Denial of Services (DoS), Memory Exhaustion (ME) threats propagate in computer network, these attacks can be remedy with the help ofproposed algorithm known as enhanced 4-way handshake approach in IEEE802.11i. Enhanced 4-way handshake process made to reduce
these types of attacks Denial of Services (DoS), Memory Exhaustion (ME). Proposed algorithm simulates and gives better result instead of existing 4-way handshake algorithm. The proposed algorithm is secure and efficient algorithm for IEEE802.11i 4-way handshake process.
