ECC-based image encryption using code computing

Abstract

To ensure the security of image interaction, a new image encryption scheme based on code computing and elliptic curve cryptosystem (ECC) is presented. First, a code matrix A is obtained by encoding the original image. Second, a new code matrix C can be obtained by performing the code addition operation among the interval elements of A. Third, divide C into some datum packages with equal length. Each package adds the secret key encoded by codes. Fourth, transform these packages into a code matrix D and decode it, and then we can get the encrypted image. Finally, the secret key is encrypted by ECC. The process of decryption is an inverse process of encryption. The experimental results and security analyses show that our scheme cannot only achieve good encryption, but also resist the exhaustive, statistical and differential attacks. © 2013 Springer-Verlag.
