How Is Cryptography Used Today?
Cryptography or cryptology is a Greek word that means ‘hidden’. The verb form of the word, interestingly means ‘write’ and the term eventually stands for the exclusive study of message secrecy. Today, cryptography has become a branch of information theory and is used within a mathematical approach to study the transmission of information from place to place. The science of cryptography involves communication in the presence of adversaries. It even enhances the spheres of engineering and pure mathematics. It plays a very important role within the spheres of information technology, authentication and access control. Cryptography involves the hiding of the specific meaning of messages, but not their existence. The study also contributes to the development of computer science, particularly in the techniques used in network securities. It is crucial in application in the spheres that involve extensive and sensitive levels of access control and information confidentiality. Cryptography is al
