Design principles of block ciphers

Webdesign of KLEIN [22] and in the design of LED we have aimed at very compact hardware implementation while maintaining some software-friendly features. Our new block cipher is based on AES-like design principles and this allows us to derive very simple bounds on the number of active Sboxes during a block cipher encryption.
