Cryptography is the study of techniques for ensuring the secrecy and authentication of the information. In this paper use two algorithm RSA and ECC cryptography to encrypt and decrypt the video file. Elliptic Curve Cryptography recently gained a lot of attention in industry. The principal attraction of ECC compared to RSA is that it offers equal security for a smaller bit size, thereby reducing processing overhead .In RSA we firstly generate key pair and secondly encryption decryption algorithm to encrypt and decrypt the video then apply ECC algorithm to encrypt/decrypt of encrypted/decrypted RSA video. It gives more and more security to our video file. Elliptic curve arithmetic can be used to develop a variety of elliptic curve cryptographic (ECC) schemes including key exchange, encryption and digital signature. The mathematic background of ECC is more complex than other cryptographic systems just as Geometry, abstract algebra, number theory. ECC provides greater security and more efficient performance than the first generation public key techniques (RSA and Diffie-Hellman), Mobile systems, Systems required high security level (such as 256 bit AES).
