How to prove you know a discrete logarithm

The article details the discrete logarithm problem in finite groups and presents a protocol for creating a zero-knowledge proof. It walks through the steps where a prover convinces a verifier they know a secret exponent x (where b^x = y) using random challenges and responses, without disclosing x itself, leveraging the computational difficulty of the discrete logarithm.
