Discrete Logarithm based Public-Key Cryptosystem: Diffie-Hellman Key Exchange & ElGamal Encryption

The mathematics behind the Diffie-Hellman key exchange underpins ElGamal encryption. The ElGamal public-key cryptosystem is based on the computational hardness of discrete logarithms, so it is vulnerable to quantum cryptanalysis.
