Abstract

" MéTODO E DISPOSITIVO PARA GARANTIR A INTEGRIDADE E A AUTENTICIDADE DE UM CONJUNTO DE DADOS ". Cada unidade receptora compreende um decodificador (IRD) e uma unidade de segurança (SC) assim como meios de comunicação (NET, REC) como o centro de gestão. O método consiste em calcular uma informação de controle (Hx) representativa do resultado de uma função dita unidirecional e em colisão, efetuada sobre a totalidade ou parte de dados transmitidos e em transmitir o resultado ao centro de gestão para verificação. O centro poderá informar ao decodificador sobre a autenticidade dos dados pelas vias do retorno pela via principal.
