Abstract

"DISTRIBUIçãO óTICA DE CHAVE FORA DE BANDA". Um aspecto da divulgação diz respeito a um sistema de comunicação fora de banda e ao processo associado. O sistema de comunicação fora de banda inclui um caminho de dados criptografados que é configurado para transferir dados criptografados. O sistema de comunicação fora de banda inclui um canal fora de banda ótico que é fisicamente distinto do caminho de dados criptografados. O caminho de dados criptografados estende-se entre um transmissor ótico e um receptor ótico. O canal fora de banda ótico é configurado para transmitir informação da chave do transmissor ótico para o receptor ótico.
