A Review Paper on Network Security and Cryptography
Cryptography is the science of information security that includes techniques such as microdots, merging words with images, and other ways to hide in order in storage or transit.
Abstract
Cryptography is the science of information security. The word is derived from the Greek kryptos, meaning concealed. Cryptography includes techniques such as microdots, merging words with images, and other ways to hide in order in storage or transit. Modern cryptography intersect the disciplines of mathematics, computer science, and electrical engineering. Applications of cryptography include ATM cards, computer passwords. Cryptology prior to the modern age was almost one and the same with Encryption, the translation of information from a understandable state to apparent nonsense. The sender retained the ability to decrypt the information and therefore avoid redundant persons being able to read it.
