Multimedia Data Transmission Using Elliptic curve Cryptography

As multimedia application are used in daily life, security has become most important issuse. So using ECC sending of multimedia data (text, image, audio, video) is described. ECC is mainly used for security and it uses smaller key compared to other algorithm such as RSA, Diffie Hellman. In this paper we have presented the architecture for security of multimedia data, text and image encryption and decryption is done using Koblitz method, video encryption and decryption is done using ECC and RC5, audio encryption and decryption is done using ECC. ECC is also used for various application such as phone, PDAs, Pagers, Smart cards etc.
