Improved Performance for MANETs using Cryptography

Abstract

The idea behind network security and cryptography is to safeguard wireless networks and data transmission. The network administrator controls network security, which includes granting access to data within a network. Users can access information and programs within their authority by selecting or being given an ID, password, or other authenticating information.  Numerous computer networks, both public and private, that are utilized in daily tasks to carry out transactions and communications between companies, governmental organizations, and individuals are covered by network security. Some networks may be accessible to the general public, while others may be private, like those found within businesses. Organizations, businesses, and other kinds of institutions are all involved in network security. We also examined the fundamentals of cryptography in this paper. Cipher-based cryptographic systems are explained.
