Abstract ■

In this manuscript, we have explored how the use of DSP blocks in the implementation of two authenticated-encryption modes of AES can optimize the PAR figures. Our results reflect that a 20.98 \% reduction in slice utilization can be achieved at a throughput higher than 25 Mbps (12 MHz) in the Artix-7 XC7A200TL FPGA.
