CRYPTOGRAPHIC TECHNIQUES- ESSENTIAL APPLICATIONS IN NETWORK ADMINISTRATION

Abstract

Network Security is the most vital component
in information security because it is
responsible for securing all information
passed through networked computers.
Network Security refers to all hardware and
software functions, characteristics, features,
operational procedures, accountability,
measures, access control, and administrative
and management policy required to provide
an acceptable level of protection for
Hardware and Software , and information in
a network. Only one particular element
underlies many of the security mechanisms in
use: Cryptographic techniques; hence our
focus is on this area Cryptography.
Cryptography is an emerging technology,
which is important for network security.
Research on cryptography is still in its
developing stages and a considerable
research effort is still required for secured
communication.
