Abstract

"INTEROPERAçãO BASEADA EM CORRETOR COM EMPREGO DE CERTIFICADOS HIERáRQUICOS". Trata-se de um método para Autenticação, Autorização e Contabilidade (AAA) em uma interoperação entre pelo menos duas redes (210 e 220) . As pelo menos duas redes são capazes de comunicar-se com um corretor (230) e incluem um certificado de primeira rede e de segunda rede (220) para usuário de um dispositivo de usuário que corresponde ao usuário da primeira rede (210). O certificado de primeira rede para usuário é assinado por uma chave privada de primeira rede e inclui um certificado de corretor (230) para primeira rede e uma chave pública de usuário. O certificado de corretor (230) para primeira rede é assinado por uma chave privada de corretor (230) e indica uma chave pública de primeira rede (210). Uma chave de sessão é enviada da segunda rede (220) ao dispositivo de usuário quando se determina que o certificado de corretor (230) para primeira rede (210) e o certificado de primeira rede (210) para usuário são autênticos pela segunda rede (220) com base na chave pública de corretor (230) e na chave pública de primeira rede (210), respectivamente. A chave de sessão é criptografada com a chave pública de usuário. A chave de sessão é para permitir que o dispositivo de usuário acesse a segunda rede.
