Mar 16, 2017 at 12:11 | comment | added | Richie Frame | @Raza a timing attack requires correlations to be calculated between timing averages. If you have 4096 s-box entries vs 256 s-box entries, more data and computation is required to perform the correlation analysis. Having more entries could also possibly make the attack easier, depending on the CPU. | |
Mar 16, 2017 at 7:28 | comment | added | crypt | you said, "S-box table lookups are a problem for cache timing consistency, they can reveal plaintext or key material. Multiple s-boxes can make it more difficult to mount such an attack, but s-box free designs can eliminate them" Please explain, how the more sboxes will help against cache timing attack? | |

May 30, 2016 at 18:38 | comment | added | crypt | Thanks a lot for such a nice explanation :) Here i got another issue, can you explain this (crypto.stackexchange.com/questions/35679/camellia-key-schedule) specially the last line of question, " does Camellia Keyschudule have it?" | |
