Abstract

"MéTODOS E APARELHO PARA COMUNICAçãO SEGURA POR PROTOCOLO INTERNET EM UM SISTEMA DE PROCESSAMENTO DE CHAMADA". Técnicas para proporcionar comunicações seguras entre duas ou mais unidades terminais de um sistema de processamento de chamada por meio de um complexo de chamada ou outra comutação de sistema de comunicação. Cada uma das unidades terminais, gera um conjunto de listas de chaves de sessão incluindo uma lista de sessão baseada em empilhamento para cada um dos terminais acoplados nela. Os múltiplos conjuntos de listas de chaves de sessão são comunicados a partir das unidades terminais para o complexo de chamada de uma maneira segura como parte dos protocolos correspondentes de autenticação realizados entre as unidades terminais e o complexo de chamada. Ao estabelecer comunicações seguras entre uma unidade terminal de origem e uma ou mais unidades terminais, o complexo de chamada seleciona, como uma chave de sessão de unidade terminal para unidade terminal, uma chave de sessão de uma lista de chaves de sessão em um determinado conjunto dos conjuntos de listas de chaves de sessão associados à unidade terminal de origem. A unidade terminal selecionada para chave de sessão de unidade terminal é usada para proporcionar comunicações seguras entre a unidade terminal de origem e, pelo menos, uma outra unidade terminal por meio do complexo de chamada. A mesma chave de sessão da unidade terminal para unidade terminal é usada, de preferência, para quaisquer unidades terminais adicionais subseq³entemente conferenciadas no canal seguro de comunicação entre a unidade terminal de origem e uma unidade terminal especificada de destino. Ao término do canal seguro de comunicação, uma ou mais novas chaves de sessão podem ser geradas para os terminais afetados de modo a manter um tamanho mínimo de empilhamento desejado para as listas de sessão.
