Cryptology is the science that aims to provide information security in the digital world. Cryptology is usually split up into two closely related fields: cryptography and cryptanalysis. Cryptography studies the design of algorithms and protocols for information security. Cryptanalysis is concerned with this study of mathematical techniques that attempt to break cryptographic primitives. Research on cryptography is still in its developing stages and a considerable research effort is still required for secured communication. The objective of this Book is to explain the Modern cipher techniques and also for their performance evaluation of this cipher techniques based on information theory tests.
