Most of the hardware and software products and standards that use public key technique for encryption, decryption, authentication etc. are based on two major cryptosystem RSA and ElGamal cryptosystem. This paper involves the development of elliptic curve cryptography for point doubling, point addition and scholar multiplication. The authors presented the timing details for different bit length for 10000 operations and compare the performance of ElGamal encryption & decryption over EC (Fp) and Fp at the different security levels.
