WebNov 8, 2024 · In my opinion, Cryptography is a research area neither as theoretical as math nor as practical as information security. But Cryptography plays a role to connect them somehow. So math background can be helpful, but cryptography has its own "language". Crypto seems to cover everything related to security that can be formally proved. WebCryptography is the study of secure communications techniques that allow only the sender and intended recipient of a message to view its contents. The term is derived from the Greek word kryptos, which means hidden.
WebCryptography 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 information security services.
