Abstract

"MéTODO DE FORNECIMENTO DE INTERFACE EM UMA REDE DE TELEFONIA DE BANDA LARGA". A interface de telefonia de banda larga é fornecida pela recepção de informação que autentica um servidor de fornecimento, estabelecendo um canal de comunicação entre o usuário e o servidor de fornecimento pelo qual é transmitida informação de autorização do usuário para o servidor de fornecimento, e a criptografia e a transmissão de uma chave criptográfica associada ao usuário do servidor de fornecimento. A chave criptográfica pode ser uma chave simétrica ou uma chave pública que corresponde a uma chave privada armazenada na interface de telefonia de banda larga. A chave criptográfica pode ser utilizada para gerar outras chaves que são utilizadas para assegurar os canais de comunicação para o serviço de telefonia. A interface de telefonia de banda larga pode ser vantajosamente implementada como hardware ou software não confiados que são instalados por um cliente.
