Title: strange curve anomaly Post by: interiawp on January 07, 2022, 12:17:29 PM Before I was sure that secp256k1 has 256bit security for all bits (of integers).
But. I found strange curve anomaly beetween 190 bit and 240 bit. where security is up to 512 bit. I mean security as 3*sqrt(p*n) where p and n are secp256k1 modulus and orders and only for integers beetween range 190 and 240 bit how to explain? edited: must be : 2*sqrt(p*n) not 3*sqrt(p*n) Title: Re: strange curve anomaly Post by: COBRAS on January 07, 2022, 12:31:53 PM Before I was sure that secp256k1 has 256bit security for all bits (of integers).

Elliptic curves have a security that is half their prime bit length. For example a 256-bit curve has 128 bits of security. I believe that is because all algorithms used to break them have a complexity of O(2n/2).Quote integers beetween range 190 and 240 bit You can't talk about the curve's security if you have selected a limited range.Title: Re: strange curve anomaly Post by: mamuu on January 08, 2022, 12:14:03 PM hi
please show us secret priv key for proof -> sha256(7*char) tihs example for you Code: pubkey, Title: Re: strange curve anomaly Post by: mamuu on January 08, 2022, 01:05:12 PM first mamuu it is not about cracking, algo is designed for veryfing "some" math hipoteses only, . second who are you that I must proof you anything my little scriptkiddy guy , you are like "parasite" :) what have you done, what kind of test have you performed? what kind of "paper" or literature have you publish? to be sure that you will understand " no one on this forum will give you a clue or "real working script" or soultion if "exists"" and this topic is only for people who knows what I'm talking about, not for like you "proof" proof" .Go HOME little boy. Please keep your bad words to yourself, my purpose is not to argue, but to see examples, there is no hypothesis, there is a guess. hypotheses are also exemplified. cannot be left blank. Besides, what I wrote to you is already an anomaly. (https://blog.trailofbits.com/2020/06/11/ecdsa-handle-with-care/) If you don't like it, just let me know. I will not reply after this message. have a nice day |
