Abstract

GERAçãO DE CHAVE EM UM SISTEMAS DE COMUNICAçãO Um sistema de comunicação gera uma Chave de Sessão Principal (MSK) para acessar uma intidade de sistema que não fornece criptografia para tráfego. Ambos o servidor local e o usuário geram a mesma MSK. A MSK é utilizada para gerar chaves de criptografia para o tráfego. Em uma modalidade a MSK é gerada utilizando-se a função de hashing e informação específica para o solicitante. O servidor local determina a necessidade de se gerar a MSK com base na informação contida em uma mensagem de solicitação de acesso. Uma vez gerada, a MSK é fornecida para a entidade de sistema para permitir que a entidade criptografe as comunicações.
