Information Security with Cryptography

Abstract

Cryptography and Information Security help to protect data and network. Information security is the concept of transferring information over the wireless network in secure way. Nowadays transferring information from one place to another place can be easier but providing security for our information is quite difficult. Information security helps to protect our information form unauthorized users and attackers. Cryptography is a tool which satisfies information security over the computer network. Cryptography achieves information security by using encryption and decryption methods. Encryption is a process of converting original data into unreadable format and decryption is a process of converting unreadable format into readable format. In this paper we discuss about how cryptography provides secure data transmission over the Internet.
