Old With New … ElGamal and Elliptic Curve Cryptography

The original ElGamal method used discrete logarithms but had interesting properties, such as creating authenticated encryption and implementing homomorphic encryption. But, elliptic curve cryptography came along and provided much smaller keys and faster operations. So, now, we can merge the two, and open up a whole world of privacy and trust.
