CIKS-1 is a latest published block cipher based on DDP transformations. In this paper, an area optimized architecture and the FPGA implementation of this cipher are proposed. The proposed architecture introduces an area-optimized combination of the different encryption and decryption schemes of CIKS-1 algorithm. The comparisons of the introduced design with the conventional architecture prove that the proposed architecture allocates 20-30% less area and it is better by about 14% in the Area-Delay product. The Performance/Area ratio proves that the proposed architecture is superior to the conventional by about 25%. Detailed performance analysis results are presented. The proposed implementation is designed on a pipelined architecture and reaches throughput value up to 2.5 Gbps. The achieved high throughput ensures fast encryption and it is suitable for networks with hard performance demands. ER -
