Elliptic Curve Cryptography for ciphering images

The growing dire need for more and more secure systems has led researchers worldwide to discover and implement newer ways of encryption. Public key cryptography techniques are gaining worldwide popularity for their ease and better strength. With the rapid developments of the communication and applications of multimedia techniques in recent years lead the researchers to focuses on the security of digital data over the internet. In this paper we have discussed the use of Elliptical Curve Cryptography for ciphering color images. ECC has been proved to score over RSA on the basis of its strength and speed. In this paper we have used NIST Curves for ciphering color image.
