The Papers That Changed Cybersecurity, And Still Do

Okay, the RSA and Diffie-Hellman papers fundamentally changed the world of cybersecurity and brought us confidentially and assurance aspects. But cybersecurity should also be about the privacy of data and only giving away enough information that is necessary for a task to be performed. And, so, there is one research paper that stands head over heals above others in this respect, and it defined the Fiat-Shamir method:

And, also in Schnorr’s paper on signatures:

and the magical bit of the Schnorr paper is this:

And where we have “y:=r+se”. This little operation then allows us to create a proof of knowledge. These days, we do not use discrete logarithms for our implement, so let’s implement this with elliptic curve methods.
