Message Integrity and Message Authentication


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

ns2 source code for safety message broadcast protocol in vanet

Abstract

Most safety-related applications targeting at Vehicular Ad-hoc Networks (VANETs) use Vehicle-to-Vehicle (V2V) broadcast method to disseminate safety-related information to all surrounding vehicles. However, the conventional broadcast schemes have the broadcast storm problem which can lead to unbearable transmission delay and packet loss. In this paper, we present an efficient broadcast scheme referred as Vehicular Multi-hop broadcasting Protocol (VMP) for fast disseminati ....etc

Broadcasting is a common and basic operation used to support various network protocols in wireless networks. To achieve energy-efficient broadcasting is especially important for ad hoc wireless sensor networks because sensors are generally powered by batteries with limited lifetimes. Energy consumption for broadcast operations can be reduced by minimizing the number of relay nodes based on the observation that data transmission processes consume more energy than data reception processes in the sensor nodes, and how to improve the network lifeti ....etc

Aim:
To write a program to print Hello World in CORBA.

Algorithm:
Step 1: Start the process
Step 2: Create an idl class in a module Hello1and declare a
method sayHello().
Step 3: Create an implement class HelloImpl which extends
_HelloImplBase and import the module.
Step 4: Define the sayHello method and return the result.
Step 5: Define the client program named HelloClient which
imports the module
(i) Declare a static reference for interface Hello
(ii) Create and initialize the ORB and get the roo ....etc

Painting is the practice of applying paint, pigment, color or other medium to a solid surface (support base). The medium is commonly applied to the base with a brush, but other implements, such as knives, sponges, and airbrushes, can be used.

Painting is a mode of creative expression, and the forms are numerous. Drawing, gesture (as in gestural painting), composition, narration (as in narrative art), or abstraction (as in abstract art), among other aesthetic modes, may serve to manifest the expressive and conceptual intention of the pract ....etc
