Using Lightweight Dynamic User Authentication Scheme

In Extensible Authentication Protocol, a random set of authentication mechanism is used such as using smart cards or certificates or using user’s credentials. Primarily the WLAN uses EAP for the purpose of passing messages during the authentication process.

The network level security will form the relationships of authentication, encryption and authorization for the wireless network and its connectivity between wireless clients to the internal network. Some recommendations are:

Authentication: 802.11 defines authentication services to control LAN access to a level equal to a wired link because wireless LANs have limited physical security to prevent unauthorized access. Every station, whether part of an independent BSS or an ESS network, have to use the authentication service prior to establishing a connection with another station with which it wishes

Individual users play an important role in any form of institution or organization but concerns are raised about the security. The network administrators clearly lay down a set of rules, regulations and protocols that an individual user has to agree accordingly upon which part of the resources and what class of service that the user can obtain.

1.Basic Authentication- Basic authentication is one of the two mechanisms in HTTP 1.1 specification . It required the safe http communication i.e. https communication for encoding.

The most common method to authenticate the individual or users is to use the password. To Secure the network they must use strong passwords. It must be at least eight characters combination of digits, alphabets and symbols. The password prevents the user accounts from being

The authentication method used to verify the user (and server) credentials on WPA/WPA2-Enterprise networks is defined in the IEEE 802.1X standard. This requires an external server called a Remote Authentication Dial In User Service (RADIUS) or Authentication, Authorization, and Accounting (AAA) server, which is used for a variety of network protocols and environments including

I am reading Tape by Steven Camden. So far, the main, characters, Ameliah and Ryan, are both facing troubling issues in their social/family life. Ryan’s issue is him still adjusting to his stepmother, Sophia, and her problematic son, Nathan. Ameliah, on the other hand, is trying her best to fit in with the ‘popular’ girls at her school. The characters are relatively the same age but Ryan lives in 1993 and Ameliah in 2013.

Abstract - Wireless Sensor Networks (WSN) comprises of several tiny, low-cost, resource constrained sensor nodes. These nodes are placed in harsh environments and generally are used for air pollution monitoring, water quality monitoring, industrial monitoring, health monitoring and more. Routing is difficult in such surroundings primarily due to the unique constraints the wireless sensor networks suffer from. Wireless sensor network is highly dynamic, making existing routing protocols ineffective. This paper concentrates on energy efficiency of the protocols. Both the protocol presented are hierarchical and cluster based. Both have sensor nodes and a base station (BS). The BS selects the Cluster Heads (CH) among themselves. CH is the elected sensor node which passes on the sensor data collected by sensor nodes of its cluster to either BS or other CH. All candidate nodes for becoming CH are listed, based on the various factors like relative distance of the candidate node from the Base Station, outstanding energy level, possible number of neighboring sensor nodes the

3. What is an ad hoc network? In this network, the wireless clients (stations) communicate directly with each

RADIUS server’s support 's various types of authentication methods to allow a user to have authenticated access, by using the user’s username and password. Some of these authenticated methods are the Point-to-point protocol (PPP), Password Authentication Protocol (PAP) or Challenge Handshake Authentication Protocol (CHAP) and there are other methods of authentication that could be used with RADIUS.

Wireless sensor nodes[2] have limited resources such as limited memory and limited power. There is unreliable communication in wireless sensor network that leads to threat to sensor security. The security of network depend on communication which relies on protocol.

Authentication is the only method which protects information or data of an individual or organization from a second party to access. Based upon the confidentiality of that particular data or information, the level of authentication depends. Now-a-days, all this data and information what we are talking about is getting digitized all around the world. For this digitized data or information to be secure, a proper authentication procedure must be set. This arise the need for an authentication secret which belongs to the category “Something we know” to come into picture. These secrets authenticate each secret holder as the authorized legitimate user to access their particular account. Technology is

The main goal of communication protocols in WSNs is to maximize energy efficiency in order to
