For example, in a digital image, the least significant bit of each word can be used to comprise a message without causing any significant change in the image. Key clustering is a situation in which a plaintext message generates identical ciphertext messages using the same transformation algorithm but with different keys. Cryptology encompasses cryptography and cryptanalysis. The Vernam Cipher, also called a one-time pad, is an encryption scheme using a random key of the same size as the message and is used only once. It is said to be unbreakable, even with infinite resources.<br \/>\nSource: KRUTZ, Ronald L. &#038; VINES, Russel D., The CISSP Prep Guide: Mastering the Ten Domains of Computer Security, John Wiley &#038; Sons, 2001, Chapter 4: Cryptography (page 134).<\/div>\n<p><\/strong><\/span> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>What can be defined as secret communications where the very existence of the message is hidden?
