comment If its possible to derive the public key from a private key, why can't we go in reverse?
I see. There is more than one notation style. That has been confusing me for quite some time, as I cross reference my books.

I'm not sure if this kind of key recovery applies to the 3 scenarios. Again this is all self study so if you have a better path to learning, please do share.

@CodesInChaos Thanks. From my algebra background I see A = aG as simple variables. Is the difficulty inherent in the fact we're looking at a multiplicative cyclic group? My intent with this question is to study the simplest approaches to key recovery with crypto the following categories: 1: integer factorization, 2: discrete logarithm, 3: ECC discrete logarithms.

comment What is a Non-Interactive Zero Knowledge Proof?
Would this MAC for anonymous credentials be considered a non-interactive ZK proof?

@DrLecter I just added details on my use-case

@nightcracker , I suppose what I'm looking for is a "non-interactive" zero knowledge proof.

@DrLecter I'll take a look at those papers, but I was thinking of something like TOTP, where the private key signs the current time in 10 minute intervals, and that output be 2^92 secure. Replacements for TOTP is what I was looking for
