A Novel Public Key Image Cryptosystem Based on Elliptic Curve and Arnold Cat Map
Ling Jiao Chen, Ao Dong Shen · Advanced materials research · 2014
For decades, symmetric cryptosystems, such as chaos-based ones, are designed for image encryption. In this paper, a novel public key scheme for image encryption is presented. Based on the improved elliptic curve cryptosystem and Arnold cat map, the novel scheme can offer high security while avoid exchange and distribution of secret keys. The experiments illustrate that the presented scheme is computationally less complex than the traditional asymmetric cryptosystems and suitable for large image encryption.
