Abstract—The development in mobile devices and wireless technologies opens up unlimited choices of mobile services such as mobile commerce. These advances make access services available and convenient everywhere at any time. Since mobile users usually move, accessing services becomes unavailable especially in some locations that are not covered by their home networks. Therefore, it becomes necessary to roam into foreign networks in order to access such services. However, authenticating visiting users by a foreign network results in some security concerns. This challenge lies in the fact that a foreign network provider does not initially have the authentication credentials of the mobile users. The existing approaches are either roaming …show more content…
MUs always ask for a higher speed at a lower cost, and demand to be “Always Best Connected” [2]. However, due to the differences in wireless technologies, it is hard to achieve both high data rate and wide coverage at once. Moreover, different technologies sometimes are operated by multiple network providers. As a result, ubiquitous wireless network is not feasible with a single technology and a single wireless provider. That makes a MU always in need to connect to different types of technologies and service providers depending on his/her location and the target speed. However, there are some security concerns raised from the MU and foreign network (FN) perspectives as they cannot establish a connection without being authentic to each other. The traditional solution to such a problem is to have a roaming agreement between the home network (HN) and FN for verification process. Fig.1 illustrates the problem.
Roaming agreement-free challenge.
Problem Statement. A key challenge in such a heterogeneous networks environment is the possibility of roaming to administrative domains without a pre-established roaming agreement with a MU’s home domain [3]. In other words, authenticating unknown users by FN providers and preventing unauthorised access are critical concerns.
The rest of this paper is structured as follows. It starts with a review of existing approaches to the problem (Section 2). This will be followed by an overview of the

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:
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.
Outline a wireless network and technology that you use regularly. The WLANs which are derived from the IEEE 802.11 standards, and marketed under the Wi-Fi trademark name. The WLANs security is neither forthright/candid nor simple, and it is continuously varying. Even though, as WLAN increase client output, they also expose the networks to a new group of potential hackers. With the present inherent security weakness of the 802.11 standard, all companies, small, medium or large, need to find out their security conditions derived from the applications using the WLAN. The standards also provide requirements for high-speed networks that support most modern-day applications. What sorts of security issues do
Guidelines: It’s always best to introduce a paper to the reader. It sets the tone and provides an overview of what will be covered and what the goals are.
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
With the rapid increase in the number of attempted breaches and resulting damages, there is an increased need for user authentication, especially with numerous unknown mobile devices with which consumers are using to access to IT resources.
In the recent years, wireless technologies have taken a new dimension in the ways society lives. Wireless broadband is available to everyone. Whether the users are at home, driving the car, sitting in the park, and it would even work while people are a pleasure boat ride in the middle of a lake. And because of this, the need to have information at any time and be connected in all places, all the time has been satisfied.
Therefore, it is essential to address issues like security of the banking transactions that are executed from a distant place and transmitted over the air. Besides this, it is also important to ensure the security of financial transactions, if the device is stolen by hackers. If these concerns are properly addressed, then it would help increase the popularity of mobile banking by instilling a sense of trust among the customers.
There are no questions about this approach in the outline of the assignment, so the following comments should be considered “back of an envelope” considerations.
Thesis; Along with the efficiency mobile devices render, come along its risks, in which raises substantial security and privacy concerns. It’s important to be aware of the possible threats a mobile can have, along with knowing what and how to secure information, as well as trying to prevent threats from happening.
Today’s enterprise networks are more and more likely to be Windows based or at the very least have large Windows components coexisting with other network operating systems (NOS) such as the many UNIX/Linux variants, or Novell’s NetWare. Since the time that Microsoft began offering Windows NT Server version 3.51 through today’s Windows 2003 Server and its upcoming successor, codenamed “Longhorn”, the job of centralized network authentication and administration has been built around Microsoft’s domain network architecture.
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
With the vast development and deployment of wireless mobile networks such as 3G UMTS, WiMAX and Wi-Fi , mobile networking applications enabling customers to gain network access anywhere and anytime have attracted more and more attention in our daily lives. When the basic functionalities of a wireless network have been in place, customers are now more interested in value added mobile applications over this network. Most mobile applications come with the emergence of electronic trading (mobile commerce or m-commerce), hence good secure mobile trading model must be designed to attract more mobile users for doing business wirelessly. Thus, how to integrate the mobile applications with a secure trading model becomes an important design issue, which will significantly affect the success of any value-added mobile application. This is the major topic of this project.
Mobile is a most commonly used distributed communication device. Our project describes the problem encountered with mobile distributed systems and how it can be solved and implemented for secure P2P communications (Peer-to-Peer communications). The system we have is distributed and based on object oriented architecture, where each node functions as both client and server. Once a network is established between these nodes, it is difficult to refuse an access to anyone who is within stipulated range and can see the network with their adapter. It is a set of distributed systems that communicate via short range wireless technologies. This
