Schlagwort: Cryptography

Cryptography (or cryptology; from Greek κρυπτός kryptós, „hidden, secret“; and γράφειν graphein, „writing“, or -λογία -logia, „study“, respectively) is the practice and study of techniques for secure communication in the presence of third parties (called adversaries). More generally, it is about constructing and analyzing protocols that block adversaries; various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, and electrical engineering. Applications of cryptography include ATM cards, computer passwords, and electronic commerce.
