Abstract
<B>MéTODO PARA A TRANSFERêNCIA DE INFORMAçõES SENSìVEIS QUE UTILIZAM AS COMUNICAçõES NãO SEGURAS INICIALMENTE<D> No método para a transferência das informações sensíveis que utilizam as comunicações não seguras, uma primeira parte recebe uma chave pública de uma segunda parte, produz um resultado da codificação através da realização da codificação provida de chaves em no mínimo um primeiro número aleatório utilizando a chave pública, e transfere o resultado da codificação à segunda parte através de um canal de comunicações não seguras. A segunda parte decodifica o resultado da codificação para obter o primeiro número aleatório. As informações da autorização são então transferidas a partir da primeira à segunda parte através de um primeiro canal de comunicação estabelecido utilizando-se o primeiro número aleatório. As informações sensíveis são transmitidas mais adiante a partir da segunda parte à primeira parte através de um segundo canal de comunicação codificado e autenticado estabelecido utilizando-se o primeiro número aleatório se a segunda parte aceitar as informações da autorização. Numerosos pedidos existem para o sistema e para o método, incluindo a aplicação sem fio caracterizada pelo fato de que a primeira parte é um móvel e a segunda parte é uma rede.
