In this paper, we propose a new Cellular Automata (CA) based scalable parameterized hash function family named CASH. The construction of CASH is inspired by sponge function and the internal round transformation employs linear CA. For the first time, we have managed to merge the classical add-round-constant and subsequent diffusion layers. The primitive function of CASH family is proved to be secure against the state-of-the-art attacks. All the designs are implemented on Xilinx Virtex-6 FPGAs and compared with the best reported results in literature. The results show that CASH outperforms the SHA-3 finalists with respect to throughput and throughput/area.
