Network security using cryptography

Abstract: Cryptography is the science of information security. The word stands resultant from the Greek kryptos, meaning concealed. Cryptography contains techniques such as microdots, merging words through images, and other ways to hide in order in storage or transfer. Modern cryptography interconnects the disciplines of mathematics, computer science, and electrical engineering. Applications of cryptography contain ATM cards and laptop passwords. Cryptology before the modern age was almost the same as Encryption, the translation of information from an understandable state to apparent nonsense. The sender retained the ability to decrypt the data and avoid redundant persons being able to read it.

Keywords: Security, Cryptography, Decryption, Encryption.
