In this research Elliptic Curve ElGamal (ECEG) cryptosystems was studied. The ElGamal signature algorithm is similar to the encryption algorithm in that the public-key and private-key have the same form; however, encryption is not the same as signature verification, nor is decryption the same as signature creation as in RSA. The DSA is based in part on the ElGamal signature algorithm.
