ms have more useful and practical applications.
Disadvantages:
 Consumes time if image file size is large.
 Not fit if network speed is slow.
Proposed System:
The proposed encryption algorithm:
The image encryption algorithm includes two steps. Firstly, the image fusion is completed between the original-image and the key-image. Then the pixel values of the fusion-image are encrypted by Henon chaotic system.
Image fusion:
Graphics fusion technique can be used in image fusion. According to the image pixel, ..................[:=> Show Contents <=:]

audio data using the conventional methods of cryptography has certain limitations in the cryptographic strength and large computational effort due to huge amount of data and high correlation among pixels. Some of the popular public key encryption methods, such as RSA, El Gamal are not suitable for encryption of large data files and images, because their encryption rate is slow. Moreover, the security of such public key cryptographic schemes relies on the inability to perform factorization of large numbers or to solve the discrete logarithm problem in a fast, efficient manner.

Standard (AES) Rijndael algorithm have recently
been the object of an intensive evaluation. Several
papers describe efcient architectures for ASICs1
and FPGAs2. In this context, the highest effort was devoted
to high throughput (up to 20 Gbps) encryptiononly
designs, fewer works studied low area encryptiononly
architectures and only a few papers have investigated
low area encryption/decryption structures.
However, in practice, only a few applications need
throughput up to 20 Gbps while exible and low cost
