IEEE 802.1X Standard and EAP Authentication Schemes

Abstract Authentication risks are common reasons why network users are left frustrated when attackers exploit vulnerabilities. With increasing number of network attackers, there is a necessity for reliance on authentication technologies that offer the greatest efficiency in terms of denying access to unauthorized users. IEEE 802.1X and Extensible Authentication Protocol play a major part in mitigating authentication risks including providing a framework for handling issues such as changing of password by attackers, strong credentials in unprotected networks and the risk of re-using a single password for a longer-than-safe duration.

I. Introduction With the passage of time, in every area of human life, automation is penetrating more and more. From the method people commute from one place to another till the way people live in homes, lifestyles are being transformed more and more with the help of computer machines. Since past 50 years lots of researches have been done on automated cars but no one has been able to develop a safe and sound model. Cars however have been partially automated such as the ACC adaptive cruise control; Lane-adherence support and blind-spot support have been incorporated into cars at a ...

Introduction

Encryption can be defined as a process in which messages or the information are encoded in such a manner that hackers or eavesdroppers will not be able to access it. These encoded messages and information can only be read by the parties who are authorized in this respect. In encryption, the information or message (referred as plaintext) is encrypted by using an algorithm of encryption, turning the text into unreadable cipher text. This is generally done by an encryption key, which enumerates the way of encoding the text. A party, who has been authorized for encoding; however, is capable for decoding ...

Background

WEP refers to Wired Equivalent Privacy. WEP was one of the first encryption policies designed for wireless network security. WEP is a security protocol that is stipulated in the Wireless Fidelity standard, 802.11b (Networld). This is designed in such a way as to allow wireless local area network. The security level and privacy of WEP is almost similar to that of a wired LAN. For a wired local area network, defence is normally employed by physical security means. These physical security mechanisms are suitable and effective in a controlled environment such as that provided by wired local area networks. However, when it comes to ...
