MEC S-box based PRESENT Lightweight Cipher for Enhanced Security and Throughput

Abstract: Cyber Physical Systems (CPS) is essential for the integration of the physical world with the virtual electronic world. The only way to provide security to these constrained environment applications is through Lightweight Cryptography. To provide stronger security, with elevated performance and less power consumption, two PRESENT architectures are proposed in this paper. The first architecture provides the option to choose one of the three MEC S-boxes, whereas the second architecture makes use of a single MEC S-box to provide better security and increased performance for encryption and decryption processes. The Standard S-box is replaced with MEC S-box, which has its own advantages, such as, less power consumption, linear time and constant space complexity. To analyse the various parameters of the proposed architectures, they are synthesized using Xilinx Virtex-7 FPGA, in Xilinx Vivado IDE. With respect to Strict Avalanche Criterion (SAC), the standard usage of S-box, nearly gives 50% SAC whereas, at least two orders of MEC S-boxes used in the proposed architectures give more than 50% SAC for the entire algorithm, thereby increasing the security of the whole process. The results depict that the proposed architecture provides a throughput of 1564.02 Mbps whereas with a lesser power consumption.
