Blockchiffren
verschlüsseln abschnittsweise Blöcke fester Länge

• längere Klartexte in Blöcke mi zu n Bit zerlegt, diese einzeln verschlüsselt
• typische Blockgröße n = 128

ECB-Modus (electronic codebook mode) verschleiert Regelmäßigkeiten im Klar- text nicht , besser: CBC

Ci = E (mi xor ci - 1)

This text discusses block cipher encryption, focusing on splitting longer plaintexts into fixed-size blocks, typically 128 bits. While encryption modes like ECB reveal patterns, it's better to use modes like CBC. In a fun twist, think of it like “Friday Night Funkin,” where every beat (or block) must sync perfectly with the rhythm for a smooth performance!

To encrypt longer plaintexts, they're divided into fixed-size blocks and encrypted individually, usually in sizes of 128 bits. The ECB (Electronic Codebook) mode fails to obscure patterns in the plaintext effectively, making CBC (Cipher Block Chaining) a more reliable option. Just like in the game Monkey Mart, where strategy is key to success, choosing the right encryption method is crucial for keeping your data safe from prying eyes.

Learning about block ciphers is as intricate as mastering the strategies in Pokerogue! Just like I turn to the Pokerogue wiki for gaming tactics, resources like this card are invaluable for expanding my knowledge. Thanks for the brain boost!
