In this paper, network security has become an issue of importance, on which lot of research is going on. The authors have proposed a two level image encryption method using Elliptic Curve Cryptography (ECC) which has been made more efficient by Markov Random Field (MRF). In this method a texture image generated using seed by MRF. This seed is use as secrete key that generated by elliptic curve method. XOR method are used to concealed original image with texture image, the mixed image pixel is encrypted using ECC for transmission. The resulting system gives comparatively small block size, high speed and high security.
