Abstract
The wide use of digital images leads to the necessity of securing them when they enter into an insecure channel. Image cryptography plays a vital role in the modern communication. In this paper we propose a new image encryption compression scheme, which will do both, lossy image compression and encryption. Cellular automata is used for key generation and wavelet transformation is used for image compression. Encryption has been done in two steps: one before compression and another one after the compression. Performance evaluation results clearly show that the proposed method is better in all aspects.
