Cryptography system
WebMar 11, 2024 · Cryptography is used to achieve the following goals: Confidentiality: To help protect a user's identity or data from being read. Data integrity: To help protect data from being changed. Authentication: To ensure that data originates from a particular party. Non-repudiation: To prevent a particular party from denying that they sent a message. 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 in the presence of adversarial behavior.
