Cryptography terminology
WebCryptography Definition Cryptography 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. The first use of the term "cryptograph" (as opposed to "cryptogram") dates back to the 19th century—originating from "The Gold-Bug," a story by Edgar Allan Poe. Until modern times, cryptography referred almost exclusively to "encryption", which is the process of converting ordinary information (called plaintext) into … See more Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively ), is the practice and study of techniques for secure communication See more General Cryptography is widely used on the internet to help protect user-data and prevent eavesdropping.

WebThe names often use alliterative mnemonics (for example, Eve, "eavesdropper"; Mallory, "malicious") where different players have different motives. Other names are much less common and more flexible in use. Sometimes the genders are alternated: Alice, Bob, Carol, Dave, Eve, etc. [14] For interactive proof systems there are other characters: WebCryptography is a continually evolving field that drives research and innovation. The Data Encryption Standard (DES), published by NIST in 1977 as a Federal Information Processing Standard (FIPS), was groundbreaking for its time but would fall far short of the levels of protection needed today. As our electronic networks grow increasingly open ...
WebThe term cipher is sometimes used as a synonym for ciphertext, but it more properly means the method of encryption rather than the result. Decryption-Decryption is the process of taking encoded or encrypted text or other data and converting it back into text that you or the computer can read and understand. 1.2 Cryptography:Algorithms and keys WebCryptography Definition Cryptography is the process of hiding or coding information so that only the person a message was intended for can read it. The art of cryptography has been used to code messages for thousands of years and continues to be used in bank cards, computer passwords, and ecommerce.
WebCryptanalysis is the term used for the study of methods for obtaining the meaning of encrypted information without access to the key normally required to do so; i.e., it is the study of how to crack encryption algorithms or their implementations.
