Simple SIMON: FPGA implementations of the SIMON 64/128 Block Cipher

Abstract

In this paper we will present various hardware architecture designs for implementing the SIMON 64/128 block cipher as a cryptographic component offering encryption, decryption and self-contained key-scheduling capabilities and discuss the issues and design options we encountered and the tradeoffs we made in implementing them. Finally, we will present the results of our hardware architectures' implementation performances on the Xilinx Spartan-6 FPGA series.Comment: 20 page
