VLSI Implementation of Image Compression And Encryption Using SPIHT And Stream Cipher Method
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 11
Abstract
This technique is proposed for compression and encryption. Here an image is first compressed using SPIHT compression algorithm combined with Huffman coding and then the compressed image is encrypted using stream cipher. This technique is mainly used for highly efficient encryption and good compression. The Stream cipher method is chosen for their high encryption rate and they are mainly of bit-by-bit encryption. They don’t simply mean encryption but provides authenticity and integrity. Then for compression we prefer SPIHT for their unique factors such as larger bit depth, progress from lossy to lossless compression, unrestricted dimensions in image, etc. In this paper Code was simulated using Xilinx and proposed architecture is implemented using FPGA. This paper focuses mainly on highly secure encryption and high compression rate using SPIHT method in Larger Images.
