MESSAGE INTEGRITY


The cryptography systems that we have studied so far provide secrecy, or confidentiality, but not integrity. However, there are occasions where we may not even need secrecy but instead must have integrity.

Topics discussed in this section

11.1 Document and Fingerprint
11.2 Message and Message Digest
11.3 Difference
11.4 Checking Integrity
11.5 Cryptographic Hash Function Criteria

Seminar on Ad hoc networking


ABSTRACT

By definition, a mobile ad hoc network does not rely on any fixed infrastructure; instead, all networking functions (e.g., routing, mobility management, etc.) are performed by the nodes themselves in a self-organizing manner. For this reason, securing mobile ad hoc networks is challenging and, in some applications this requires a shift in paradigms with respect to the traditional security solutions for wireline networks. Meanwhile, we still rely on traditional cryptogr ....etc

ABSTRACT
 A MANET is a collection of wireless nodes that can dynamically form a network to exchange information without using any pre-existing fixed network infrastructure.
 A mobile ad hoc network is a collection of wireless nodes that can dynamically be set up anywhere and anytime without using any pre existing network infrastructure.
 It is an autonomous system in which mobile hosts connected by wireless links are free to move randomly and often act as routers at the s ....etc

ABSTRACT
In the near future, a pervasive computing environment can be expected based on the recent progresses and advances in computing and communication technologies. Next generation of mobile communications will include both prestigious infrastructured wireless networks and novel infrastructureless mobile ad hoc networks (MANETs). A MANET is a collection of wireless nodes that can dynamically form a network to exchange informat ....etc

ABSTRACT
A mobile ad hoc network (MANET), sometimes called a mobile
mesh network, is a self-configuring network of mobile devices
connected by wireless links. The Ad hoc networks are a new
wireless networking paradigm for mobile hosts. Unlike traditional
mobile wireless networks, ad hoc networks do not rely on any
fixed infrastructure. Instead, hosts rely on each other to keep the
network connected. It represent complex distributed systems that
comprise wireless mobile nodes that can freely and dynamically
self-organize into ar ....etc

Pict-Message Message Visualizer
Pict-Message is a project for people who wish to explore in an innovative and rather surprising way the different data feeds that form the building blocks of today’s virtual world. By pointing the application, let’s say, to the CNN news feed, you will receive the last news in real time - rendered in pictures. The application will choose for each in-coming word an image from flickr’s or google’s database tagged with corresponding keywords. Since the application searches and brow ....etc

Mobile Ad hoc Networking (MANET)



1. Introduction


With recent performance advancements in computer and wireless
communications technologies, advanced mobile wireless computing is
expected to see increasingly widespread use and application, much of
which will involve the use of the Internet Protocol (IP) suite. The
vision of mobile ad hoc networking is to support robust and efficient
operation in mobile wireless networks by incorpor ....etc

Abstract

Opportunistic networks are one of the most interesting evolutions of MANETs. In opportunistic networks, mobile nodes are enabled to communicate with each other even if a route connecting them never exists. Furthermore, nodes are not supposed to possess or acquire any knowledge about the network topology, which is instead necessary in traditional MANET routing protocols. Routes are built dynamically, while messages are en route between the sender and the destination(s), and any possible node can opportunistically be used as ....etc

Bluetooth Ad Hoc Networking

Abstract :

Bluetooth is an open specification for short-range wireless communication and networking mainly intended to be a cable replacement between portable and/or fixed electronic devices. The problem concerns the assignment of the roles of master and slave to each node so that the resulting MANET is connected. In this Seminar we have introduce two novel protocols for forming connected scatternets. In both cases, the resulting topology is termed a bluetree. We also address the problem of determining an opt ....etc
