The Study of Secure Communication using Cryptography Algorithms

Network and internet applications are growing in popularity daily. Security and safety procedures are needed for sensitive information. By transforming data from its original form into an unreadable one, encryption algorithms offer the required defence against attacks by data intruders. Now a days, username/password authentication makes up the majority of web authentication. Data security can be achieved via a method known as cryptography. In the past, military data was kept secure using cryptography to safeguard national security. After the advent of communication tools, the range of uses for cryptography has significantly increased today; cryptography is primarily necessary to ensure that data are safeguarded against penetrations and to prevent the practise of spying. The state of the art for several different cryptographic methods used in networking applications is discussed in this paper with help of examples.
