Abstract
"SISTEMA DE DISTRIBUIçãO DE CHAVE, E, MéTODO PARA DISTRIBUIçãO PROTEGIDA DE INFORMAçãO DE CHAVE DE CRIPTOGRAFIA DE UMA UNIDADE DE DISTRIBUIçãO DE CHAVE PARA UMA UNIDADE DE RECEBIMENTO DE CHAVE ATRAVéS DE UMA LIGAçãO DE COMUNICAçãO". A invenção se refere à distribuição segura de uma chave privada (K) de uma unidade de distribuição (1) para uma unidade de recebimento (2) e está baseada no fornecimento de cada uma dentre a unidade de distribuição e a unidade de recebimento com um circuito protetor que mantém uma chave privada original única para o circuito protetor. O circuito protetor (20) da unidade de recebimento (2) está associada com um certificado (CERT 2) mantendo informação sobre o tipo do circuito protetor. O circuito protetor (10) da unidade de distribuição solicita esse certificado para verificar a autenticidade pelo uso de uma chave pública, de uma emissão de certificado, com base na informação do tipo do certificado, se o circuito protetor (20) da unidade de recebimento representa um tipo de circuito que é aceitável para proteger a chave privada (K) a ser distribuída. Se for verificado que o circuito protetor é aceitável, a chave privada é criptografada e transmitida para o mesmo. A chave recebida é descriptografada e armazenada no circuito protetor da unidade de recebimento. Dessa maneira, a chave privada é protegida durante transferência e pode ser distribuída e protegida precisamente em uma ou mais unidades de recebimento.
