Abstract

Método de união a domínio de usuário e método de troca de informações em domínio de usuário. Método de uniâo a um domínio de usuário com base em administração de direitos digitais, método de troca de informações entre um dispositivo de usuário e um agente de execução de domínio e um método de troca de informações entre dispositivos de usuário pertencentes ao mesmo domínio de usuário incluem o compartilhamento de uma chave de sessão de domínio entre o dispositivo de usuário e o agente de execução de domínio ou entre os dispositivos de usuário pertencentes ao mesmo domínio de usuário. As informações são trocadas por meio de uma sessão segura estabelecida entre o dispositivo de usuário e o agente de execução de domínio ou entre os dispositivos de usuário e a troca de informações ocorre por meio de criptografia/decifração utilizando a chave de sessão de domínio.
