Resumo

A computação quântica ameaça a criptografia atual (RSA, ECC). O NIST padronizou algoritmos pós-quânticos (PQC) para mitigar esse risco, mas sua avaliação em blockchains com dispositivos IoT ainda é incipiente. Este trabalho avalia a viabilidade de implementar algoritmos PQC em blockchains IoT por meio de benchmarks e de simulações de verificação de blocos. Os resultados mostram que Falcon e Dilithium são os mais adequados para dispositivos restritos, enquanto MAYO apresenta desempenho insatisfatório.
