Cryptography The R3D Cipher |
| Posted: 07 Dec 2018 08:47 PM PST Hello all. I have created a block cipher based on Rijndael that uses a 3-dimensional state, a block size of 4096-bits, and has 16 rounds. I am calling it R3D, which is short for Rijndael-3D. The substitution box was changed to the one described in this paper: https://www.researchgate.net/profile/Wei_Yang106/publication/267554952_An_improved_AES_S-box_and_its_performance_analysis/links/561dffb908aec7945a253b5f/An-improved-AES-S-box-and-its-performance-analysis.pdf. I added a ShiftRows transformation at the end of the key schedule round to increase the diffusion of the round keys. I added a new transformation called ShiftSlices that is used every modulo 2 round (even round). The code implementing this cipher can be found here: https://github.com/gabemaiberger/libpqc/blob/master/r3d.c https://github.com/gabemaiberger/libpqc/. [link] [comments]  |
