T.sivakumar, R.venkatesan . A Novel Image Encryption Method with Z-Order Curve and Random Number. International Journal of Computer Applications. 103, 12 ( October 2014), 17-25. DOI=10.5120/18126-9198
Information security has become an important issue for data storage and transmission due to growth of communication development and exchange of sensitive information through Internet. The services like confidentiality, integrity, and digital signature are required to protect data against unauthorized modification and misuse by anti social elements. Image encryption is widely used in multimedia, medical imaging, telemedicine and military communications to provide confidentiality service. A novel and simple image encryption method using Z-Order (ZO) curve based scan pattern and random number is proposed in this paper. The proposed method resists the statistical and differential attacks. The method provides optimal entropy value and assures security from the additive noise and cropping attacks.
