Cryptography primitives are nothing but the tools and techniques in Cryptography that can be selectively used to provide a set of desired security services − The following table shows the primitives that can achieve a particular security service on their own. Note − Cryptographic primitives are intricately related and they are often combined to achieve a…

The primary objective of using cryptography is to provide the following four fundamental information security services. Let us now see the possible goals intended to be fulfilled by cryptography. Confidentiality Confidentiality is the fundamental security service provided by cryptography. It is a security service that keeps the information from an unauthorized person. It is sometimes…

Cryptology, the study of cryptosystems, can be subdivided into two branches − What is Cryptography? Cryptography is the art and science of making a cryptosystem that is capable of providing information security. Cryptography deals with the actual securing of digital data. It refers to the design of mechanisms based on mathematical algorithms that provide fundamental…

Modern cryptography is the cornerstone of computer and communications security. Its foundation is based on various concepts of mathematics such as number theory, computational-complexity theory, and probability theory. Characteristics of Modern Cryptography There are three major characteristics that separate modern cryptography from the classical approach. Classic Cryptography Modern Cryptography It manipulates traditional characters, i.e., letters…
