algorithms, cryptanalysis, cryptography, encryption, Security technology

Here’s an IDEA-variant with a 128-bit block length. While I think it’s a great idea to bring IDEA up to a modern block length, the paper has none of the cryptanalysis behind it that IDEA had. If nothing else, I would have expected more than eight rounds. If anyone wants to practice differential and linear … Read More “The IDEA Encryption Algorithm with a 128-bit Block Length” »
