In this paper a group theoretical ElGamal cryptosystem is introduced, which is based on a semidirect product of groups. It is developed from the key exchange protocol based on a semidirect product of (semi)groups introduced by M. Habeeb, D. Kahrobaei, C. Koupparis and V. Shpilrain. Finally, a proposal for a signature protocol is described.
