We show the latest implementation results of the block cipher SC2000, which are a software implementation on the IA-32 processors and a hardware implementation. In the software implementation, we introduce a new combination strategy of non-homogeneous S-box that is one of the characteristics of SC2000, and achieve the fast implementation of SC2000. In addition, we discuss the transition of the speed by the combination strategies of S-box. In the hardware implementation, we introduce a new architecture for fast implementation of SC2000 and show the results of our implementation. In particular, we improve the software encryption speed by 1.6 times as compared to the previous best implementation, and we achieve the speed of 1.4Gbps with the hardware of 26KGates.
