Image Encryption using Elliptic Curve Cryptography

Million of images are transferred everyday across the network. Some of these images are confidential and we want these images to be transferred securely. Cryptography plays a significant role in transferring images securely. The exponentially hard problem to solve an Elliptic Curve Discrete Logarithm Problem with respect to key size of Elliptic Curve Cryptography, helps in providing a high level of security with smaller key size compared to other cryptographic technique which depends on integer factorization or Discrete Logarithmic problem. In this paper, we implement the Elliptic Curve cryptography to encrypt, decrypt and digitally sign the cipher image to provide authenticity and integrity. (C) 2015 The Authors.
