Q: Why are public keys derived from elliptic curve cryptography (ECC) and not from hashing?

razak57I've just started studying Bitcoin and cryptocurrencies, so I might be wrong, but so far my understanding is that public keys are derived from private keys using ECDSA, in Bitcoin's case using secp256k1. This is a one-way function and is, technically, computationally safe... Until you take into a...

Q: What is a function on a Line or a Curve?

user93353I am reading up on Pairings using Elliptic curves & all the texts talk about functions on a Curve. I am finding it difficult to even figure out what they mean by "function on a curve" or "function on a line" The equation of a line or a curve itself is in the form of a function, but I am unable to...

Q: Timing attacks: Symmetric vs Asymmetric Algorithms

NB_1907There is a statement that I can't give a reference; "Since the timing characteristics of symmetric algorithms are not as key dependent as asymmetric algorithms, they are more resistant against timing attacks." Is it true?
