term modification from cygnusv comment
|
| Feb 20, 2015 at 12:09 | comment | added | Cédric Van Rompay | @cygnusv: agreed; I just coined the term quickly for the SE question, I don't intend to use that name anywhere anyway. | |
| Feb 20, 2015 at 12:06 | comment | added | cygnusv | BTW, maybe more than "collision by product resistance", your problem is "second preimage by product resistance", since you are fixing $a$ in your problem. | |
| Feb 20, 2015 at 11:59 | comment | added | Cédric Van Rompay | @Dillinur: yes, modulo. If not you don't have a group | |
| Feb 20, 2015 at 11:52 | comment | added | cygnusv | I don't think your problem is as hard as preimage resistance. In fact, I don't think it is as hard as collision resistance... | |
| Feb 20, 2015 at 10:31 | comment | added | Dillinur | Do you include modulo in your product, or do H(b) and H(c) have to be small enough so that H(a) remains in the valid output range? | |
