How does the elliptic-curve version of Diffie-Hellman cryptography work?
- by cmaduro
Does the Elliptic curve diffie hellman calculation look any different from the standard one defined here:
/*
* The basic Diffie-Hellman Key Agreement Equation
*
* The client initiates
* A = g^a mod p
*
* Sends (g p A) to the server
*
* The server calculates B
* B = g^b mod p
*
* Sends B back to client
*
* The client calculates K
* K = B^a mod p
*
* The server calucaltes K
* K = A^b mod p
*
*/
Or is it just a specific way of selecting g, a, p and b? How are g,a,p and b selected anyway?
