WebA better and more secure algorithm was required to encrypt sensitive, unclassified federal information in the U.S. In 2001, NIST encouraged cryptographers to present a more resilient algorithm to replace DES to encrypt mission-critical data. Five algorithms -- MARS, Rivest Cipher 6, Serpent, Twofish and Rijndael -- were presented. WebIn cryptography, a cipher (or cypher) is a method for protecting data through encryption …

encryption - Why is XOR used in cryptography? - Stack Overflow
WebSep 4, 2009 · I can see 2 reasons: 1) (Main reason) XOR does not leak information about the original plaintext. 2) (Nice-to-have reason) XOR is an involutory function, i.e., if you apply XOR twice, you get the original plaintext back (i.e, XOR(k, XOR(k, x)) = x, where x is your plaintext and k is your key). The inner XOR is the encryption and the outer XOR is the … WebCryptographic security: The component of communications security that results from the provision of technically sound cryptosystems and their proper use. This includes ensuring message confidentiality and authenticity. WebCryptography class offers a comprehensive introduction to Modern Cryptography, and, specifically, its main problems, formalisms, solutions, and open questions, with a heavy focus on application aspects, including case studies for real-life uses of Modern Cryptography solutions.
