High-Speed Block Cipher Algorithm Based on Hybrid Method

摘要

This paper proposes 3 different designs of the new 64-bit block cipher diagram. A new feature of the designs is the application of hybrid CSPN (Controlled Substitution Permutation network). Designs with particular advantages will make the selection more appropriate for each target of applications. However, design shall meet all the security requirements to protect applications against the well-known threats.
