Cryptography II Study guides, Class notes & Summaries

Cryptography The science of altering communication so that it cannot be understood without having the key. cipher The algorithm(s) needed to encrypt and decrypt a message. Mono-alphabet substitution Substitute one character of cipher text for each character of plain text. Caesar cipher Every letter is shifted a fixed number of spaces to the left or the right in the alphabet. Ciphertext The resultant text after being subjected to the algorithm and key. Atba...

CrypTool Software which allows encryption of text using historic algorithms The Enigma Machine In World War II the Germans made use of an electro-mechanical rotor based cipher Known as The Enigma Machine. Allied cipher machines used in WWII included the British TypeX and the American SIGABA. The ADFGVX Cipher invented by Colonel Fritz Nebel in 1918. The key for this algorithm is a six-by-six square of letters, used to encode a 36-letter alphabet. The Playfair Cipher ...

PCI Data Security Standard (PCI DSS) The PCI DSS applies to all entities that store, process, and/or transmit cardholder data. It covers technical and operational system components included in or connected to cardholder data. If you accept or process payment cards, PCI DSS applies to you. Sensitive Authentication Data Merchants, service providers, and other entities involved with payment card processing must never store sensitive authentication data after authorization. This includes th...
