Implementação e avaliação da cifra de fluxo Forro14 em hardware programável Tofino usando a linguagem P4

The software-defined networking (SDN) paradigm has enabled several innovations in computer networking, especially in programmable packet processing. This paper investigated the feasibility and impact on computing resources of the Forro14 stream cipher algorithm in the Tofino programmable hardware switch. For comparison purposes, the ChaCha20 algorithm was also analyzed in terms of its performance and impact on the same switch. It was observed that the Forro14 algorithm performs better using fewer resources than ChaCha20 for communications up to 10 Gbps. However, when parallelization techniques are adopted, ChaCha20 performs better for higher data rates but uses more processing resources than Forro14.
