Abstract : We present the construction and implementation of an 8-bit S-box with a differential and linear branch number of 3. We show an application by designing FLY, a simple block cipher based on bitsliced evaluations of the S-box and bit rotations that targets the same platforms as PRIDE, and which can be seen as a variant of PRESENT with 8-bit S-boxes. It achieves the same performance as PRIDE on 8-bit microcontrollers (in terms of number of instructions per round) while having 1.5 times more equivalent active S-boxes. The S-box also has an efficient implementation with SIMD instructions, a low implementation cost in hardware and it can be masked efficiently thanks to its sparing use of non-linear gates.
