This book was released on 2017-04 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past few years, secure information sharing became very popular in the area of immigration, military applications, healthcare, education, foreign affairs, etc. As secure communication utilizes both wireless and wired communication mechanizations for exchanging sensitive information, security and privacy of the information exchange cannot be easily compromised. To moderate the security, integrity, authenticity, and privacy issues related to information exchange, numerous authentication mechanisms have been recommended by different researchers in the literature in recent times, but these are vulnerable to prospective security flaws such as masquerade, insider, replay, impersonation, password guessing, server spoofing, denial-of-service attacks and, in addition, have failed to deliver mutual authentication. In the past few years we have also witnessed a balanced growth in the acceptance of VoIP (Voice over IP) facilities because the numerous Web and VoIP applications depend on huge and extremely distributed infrastructures to process requests from millions of users in an appropriate manner. Due to their extraordinary desires, these large-scale internet applications have frequently surrendered security for other objectives such as performance, scalability and availability. As a result, these applications have characteristically favored weaker, but well-organized security mechanisms in their foundations. Session Initiation Protocol (SIP) is an application and presentation layers signaling protocol that initiates, modifies, and terminates IP-based multimedia sessions. Implementing SIP for secure communication has been a topic of study for the past decade, and several proposals are available in the research domain. However, security aspects are not addressed in most of these proposals, because SIP is exposed to several threats and faces security issues at these layers. Probes for SIP (Session Initiation Protocol) servers have been conveyed for many years. To gather more details about these activities the author has designed a scheme for SIP servers in a network and composed data about some popular attacks. Furthermore, he explains his interpretations and guidance on how to prevent these attacks from being successful. Biometrics, a new field of research, has also been dealt with in this research by means of a “three-factor authentication scheme”, in which one factor is biometrics.

Download or read book An Improved and Robust Anonymous Authentication Scheme for Roaming in Global Mobility Networks written by Ahmed Fraz Baig and published by Anchor Academic Publishing. This book was released on 2017-04-28 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless communication systems are extensively used in the current decade. Internet based applications are accessed by mobile networks at any time and from anywhere. Nowadays, roaming in mobile communication has become extremely popular. Mobility is the function that allows a user to move around and, at the same time, stay inside the network. The Global Mobility Network (GLOMONET) plays a very important role in wireless communication. It is a commodious domain which enables a roaming user to access their home mobile services in a foreign country. While traveling, the roaming service assures that our mobile or wireless devices are connected with a network without any breakage of connection. When persons visit some other country they have to use the mobile services. In GLOMONET, the roaming user, being in a foreign country, uses the mobile services with the help of their home country network. Mobile users connect themselves to a foreign network and the foreign network verifies the legality of the mobile user through their home network and home agent. Due to the technological improvements, many security issues have been raised up. Security is the main issue in wireless communication because anyone may intercept the communication at any time. While designing the security protocols for wireless networks, communication and computation costs are very important. The objective of this study is to propose an authentication scheme that has the ability to detect and resist all possible attacks. Formal security analysis and authenticity of proposed thesis is analyzed with BAN logic and ProVerif. Furthermore, the author checked the security of the proposed scheme informally against different attacks.

Download or read book Switching to VoIP written by Theodore Wallingford and published by "O'Reilly Media, Inc.". This book was released on 2005 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: More and more businesses today have their receive phone service through Internet instead of local phone company lines. Many businesses are also using their internal local and wide-area network infrastructure to replace legacy enterprise telephone networks. This migration to a single network carrying voice and data is called convergence, and it's revolutionizing the world of telecommunications by slashing costs and empowering users. The technology of families driving this convergence is called VoIP, or Voice over IP. VoIP has advanced Internet-based telephony to a viable solution, piquing the interest of companies small and large. The primary reason for migrating to VoIP is cost, as it equalizes the costs of long distance calls, local calls, and e-mails to fractions of a penny per use. But the real enterprise turn-on is how VoIP empowersbusinesses to mold and customize telecom and datacom solutions using a single, cohesive networking platform. These business drivers are so compelling that legacy telephony is going the way of the dinosaur, yielding to Voice over IP as the dominant enterprise communications paradigm. Developed from real-world experience by a senior developer, O'Reilly's Switching to VoIP provides solutions for the most common VoIP migration challenges. So if you're a network professional who is migrating from a traditional telephony system to a modern, feature-rich network, this book is a must-have. You'lldiscover the strengths and weaknesses of circuit-switched and packet-switched networks, how VoIP systems impact network infrastructure, as well as solutions for common challenges involved with IP voice migrations. Among the challenges discussed and projects presented: building a softPBX configuring IP phones ensuring quality of service scalability standards-compliance topological considerations coordinating a complete system ?switchover? migrating applications like voicemail and directoryservices retro-interfacing to traditional telephony supporting mobile users security and survivability dealing with the challenges of NAT To help you grasp the core principles at work, Switching to VoIP uses a combination of strategy and hands-on how-to that introduce VoIP routers and media gateways, various makes of IP telephone equipment, legacy analog phones, IPTables and Linux firewalls, and the Asterisk open source PBX software by Digium.You'll learn how to build an IP-based or legacy-compatible phone system and voicemail system complete with e-mail integration while becoming familiar with VoIP protocols and devices. Switching to VoIP remains vendor-neutral and advocates standards, not brands. Some of the standards explored include: SIP H.323, SCCP, and IAX Voice codecs 802.3af Type of Service, IP precedence, DiffServ, and RSVP 802.1a/b/g WLAN If VoIP has your attention, like so many others, then Switching to VoIP will help you build your own system, install it, and begin making calls. It's the only thing left between you and a modern telecom network.
