The word Cryptography is derived from Greek kryptos, meaning hidden. Cryptography is not alone word or one word for all related information security science. Words like cryptanalysis, cipher and cryptology are always included in this science.Continue Reading Reference book: Cryptographic Algorithms generally fall into one of two different categories, or are a combination of both. Symmetric Fast Only provide confidentiality Examples: DES, AES, Blowfish, RC4, RC5 Asymmetric Large mathematical operations make it slower than symmetric algorithms No need for out of band key distribution (publicContinue Reading Cryptography What is cryptography? Cryptography (or cryptology; from Greek κρυπτός, “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 thatContinue Reading
