Abstract

In this paper, we present the realization of of partial encryption of compressed images on Altera FLEX10K FPGA device that allows for efficient hardware implementation. The compression algorithm decomposes images into several different parts. A secure encryption algorithm is then used to encrypt only the crucial parts, which are considerably smaller than the original image. This will result in significant reduction in processing time and computational requirement for encryption and decryption. The breadth-first traversal linear lossless quadtree decomposition method is used for the partial compression and RSA is used for the encryption. Functional simulations are carried out to verify the functionality of the individual modules and the system on four different images. Comparisons, verification and analysis made validate the advantage of this approach. The design has utilized 2928 units of LC and a system frequency of 13.42MHz.
