Message IntegrityandMessage 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

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

Definition
Short message service (SMS) is a globally accepted wireless service that enables the transmission of alphanumeric messages between mobile subscribers and external systems such as electronic mail, paging, and voice mail systems. The benefits of SMS to subscribers center around convenience, flexibility, and seamless integration of messaging services and data access. From this perspective, the benefit is to be able to use the handset as an extension of the computer. SMS also eliminates the need for separate devices for messaging, as se ....etc
