Abstract :
We propose a block-cipher-based hardware architecture for authenticated encryption (AE) applications supporting the Ethernet standard IEEE 802.3ba. Our main design goal was to achieve high throughput on FPGA platforms. Compared to previous works aiming at data rates beyond 100 Gbit/s, our design makes use of an alternative block cipher and an alternative mode of operation, namely Serpent and the offset codebook mode of operation, respectively. Using four cipher cores for the encryption part of the AE architecture, we achieve a throughput of 133 Gbit/s on an Altera Stratix IV FPGA. The design requires 30 kALMs and runs at a maximum clock frequency of 260 MHz. This represents, to the best of our knowledge, the fastest full implementation of an AE scheme on FPGAs to date.
