In this paper, we investigate the application of integral cryptanalysis to the Byte-oriented Substitution Permutation Network (BSPN) block cipher. The BSPN block cipher has been shown to be an efficient block cipher structure, particularly for environments using 8-bit microcontrollers. In our analysis, we are able to show that integral cryptanalysis has limited success when applied to BSPN. A first order attack, based on a deterministic integral, is only applicable to structures with 3 or fewerdoi:10.1109/qbsc.2014.6841204 fatcat:krl2muwf7velhpbwcycsdfojqq
