Abstract: In 1985 a powerful and public-key scheme was produced by ElGamal. ElGamal encryption/decryption algorithm is based on the difficulty of discrete logarithm problem where it is straight ...

Abstract: ElGamal algorithm is a well-known and important cryptosystem. Elliptic curve algori- thm became a hotspot in cryptography community, because of its safety, efficiency and low comp- lexity.
