Information security is one of the key challenges in data communication. For secure information communication over public network, different cryptographic methods are applied. There have many public key cryptography systems and they have difference performance. This system proposes the performance of the three public key cryptography systems: RSA (Rivest Shamir Adelman), ElGamal and ECC (Elliptic Curve Cryptography) by comparing encryption and decryption messages. This paper presents the implementation and comparison of RSA, Elgamal and ECC for variable text files sizes. Our goal is to calculate encryption time, decryption time, and key size based on different file size for each algorithm to identify which algorithms outperforms others in term of evaluation parameters.
