Image Encryption Using Elliptic Curve Cryptography

Elliptic Curve Cryptography or Cryptosystem (ECC) is one of the public-key cryptosystem. The main advantage and benefit of ECC instead of RSA is that it gives equivalent security by using smaller key then in RSA; thereby it consumes less number of resource and also less amount of memory. There are various advantages of ECC over RSA such as low bandwidth usage, low computational time and small key size; it can also be used for image encryption. Through this paper image encryption with using ECC is presented. It discusses the encryption, compression and decryption of image using ECC on matlab as platform.
