Wireless communication networks are in huge need and demand due to various features of internet and its availability and easy accessibility all over the world. Therefore, advanced security techniques and mechanism are required for private business application and for effective and secured data transfer from one network to other. Many common standards such as 6LoWPAN, Zigbee (IEEE 802.15.4-2006), WiFi (IEEE 802.11) and many more are being used for wireless standard. Many techniques used today having weak security and loop holes that can easily be attacked to gain access over the networks such as Wired Equivalent Privacy(WEP) can easily be stabbed with the ample availability of tools and the data present can be modified or read by the mediator. This paper aims for developing a Modified Wired Equivalent Privacy protocol (MdWEP) which will give more reliable communication and security benefits. To implement MdWEP we are using three cryptography algorithms AES, RSA and MD5. To increase the security three fold the plain text is passed through three cryptography architecture namely AES, RSA and MD5. Hardware implementation of this structure will consume more hardware and power but the speed can be increased by pipelining the output of each stage. Software implementation does not require huge resources but we get 3 times secured data. Hardware implementation is being done using xilinx and software implementation is being done by Java Swing © 2005 - 2013 JATIT & LLS. All rights reserved.
