ON NETWORK SECURITY: THE IMPORTANCE OF CRYPTOGRAPHY

Unlike past classical schemes used for the concealment of diplomatic and military secrets of monarchs and government officials at all levels, today’s cryptography must provide cost effective, secure approaches for protecting the vast amounts of digital data gathered and communicated with electronic data processing systems.

Cryptography is the art of concealing the content of messages from an enemy who may be monitoring system activity. The spread of communication-based technology and the recent appearance Of cryptographic techniques that provide highly secure message concealment, have led to a renewed interest in the field of cryptography. In the day to day life,
cryptography comes handy when Internet crooks try to steal the data from our hard drive; if our hard drive disk is encrypted instead, the hacker will have an unusable disk
because of its encryption.

Cryptography can be used to achieve file security. A protocol is developed for the encryption of data stored on removable media. Enhanced authentication protocols, including personal verification, message authentication, and digital signatures, can also be achieved through cryptographic techniques. These subjects are of particular interest to those concerned with electronic funds transfer and credit card applications within the banking and finance industry, or any other area where the originator, timeliness, contents, and
intended receiver of a message must be verified.

In the absence of strong cryptographic protection, an eavesdropping opponent may learn enough about the operational procedures of the system, including passwords, to defeat any security mechanisms.
