FPGA Implementation of Cellular Automata Based Stream Cipher: YUGAM-128

Abstract

Ubiquitous computing is fetching a significant part in everyone's life. Few such examples are the mobile communication, personal computation and portable hand held devices. The growth in ultra-low power technology enabled the new development of small autonomous mobile devices. For the wireless communication systems with these portable mobile devices, security is a critical factor due to their impact on privacy.. Traditional cryptographic algorithms are much complex and power consuming thereby unfit for this resource constrained applications. In this paper, a novel stream cipher called YUGAM-128 is designed using one dimensional cellular automata (CA) rule 30 and linear feedback shift register (LFSR). The prime aspect of the stream cipher is to generate random 128 bit keystream. The proposed stream cipher is implemented and synthesized in Spartan-3 FPGA device using Xilinx 13.2.
