Hardware realization of chaos based block cipher for image encryption
Mohamed L. Barakat, Ahmed Gomaa Radwan, Khaled N. Salama · 2011
Unlike stream ciphers, block ciphers are very essential for parallel processing applications. In this paper, the first hardware realization of chaotic-based block cipher is proposed for image encryption applications. The proposed system is tested for known cryptanalysis attacks and for different block sizes. When implemented on Virtex-IV, system performance showed high throughput and utilized small area. Passing successfully in all tests, our system proved to be secure with all block sizes.
