Abstract

"CONTROLE DO ACESSO A UMA REDE UTILIZANDO REDIRECIONAMENTO". Trata-se de um mecanismo para aperfeiçoar a segurança e o controle de acesso através de uma rede, tal como uma rede de área local sem fios ('WLAN'), que obtém vantagem das interações do navegador da rede sem requerer uma sessão de comunicação separada explícita entre uma rede de ponto de entretenimento e uma rede do provedor de serviços. o método compreende receber uma requisição para acessar a WLAN a partir de um terminal móvel (MT) / cliente disposto dentro de uma área de cobertura da WLAN. O ponto de acesso (AP) da rede associa uma ID da sessão e um número gerado de forma aleatória com um identificador associado com o MT e armazena dados mapeando a ID da sessão para o identificador do MT e o número gerado de forma aleatória. o servidor local transmite uma requisição de autenticação na forma de uma página da rede, a qual inclui a ID da sessão e o número gerado de forma aleatória, para o MT. O AP recebe a partir do MT uma mensagem de autenticação digitalmente assinada, uma lista de parâmetros contendo a informação credencial do usuário, a ID da sessão e o número gerado de forma aleatória com respeito ao MT, a mensagem de autenticação sendo digitalmente assinada utilizando a ID da sessão e o número gerado de forma aleatória junto com a lista de parâmetros. O AP correlaciona a ID da sessão e a lista de parâmetros recebida a partir do MT e, utilizando os dados de mapeamento armazenados, gera uma assinatura digital local para comparação com a mensagem de autenticação digitalmente assinada recebida para controlar o acesso do MT à WLAN.
