| | Motivation RSA (Rivest-Shamir-Adleman) is one of the first public-key cryptosystems and is widely used for secure data transmission. In such a cryptosystem, the encryption key is public and is different from the decryption key which is kept secret. If I wanted to comprehend zero knowledge proofs, then understanding the grand-daddy of public-key cryptosystems is a must. Background Maths Exponential Rules 1 $$ \begin{align} \label{eq:exponent_rule} g^{a-b} &= \dfrac{g^a}{g^b} \newline g^{a+b} &= g^a g^b \n...

| Elliptic Curves over Finite Fields What do elliptic curves in finite fields look like? It's easy to visualize smooth elliptic curves, but what do elliptic curves over a finite field look like? The following is a plot of $y² = x³ + 3 \pmod {23}$ Because we only allow integer inputs (more specifically, finite field...
