| Jul 9, 2018 at 6:00 | comment | added | sribin | @SqueamishOssifrage, I do not jury-rigging anything. I just take ECIES with sign-then-encryptand and try to understand why people do it instead of the scheme I described (ECDSA plus Kmac without MAC) becase I think making ECDSA's tag and MAC's tag more costly than making only ECDSA's tag. It is about performance. Also I have written that security goals I expected, because I take ECIES like platfrom and think about authentication by using only public keys without PKI and I do not want Eve can do that I have written in my question. Please, read my qestion more carefully. | |

Please step back from jury-rigging compositions of ECDH, KMAC, ECDSA, etc., or any specific cryptography, and write down what you're positively trying to achieve with what resources for what legitimate parties, what powers an an adversary has to subvert those resources, and what you want to ensure the adversary cannot do to the legitimate parties in spite of those powers. | |
