Abstract

MéTODO PARA PROCESSAR MENSAGENS CODIFICADAS E SISTEMA PARA VERIFICAR MENSAGENS ELETRÈNICAS CODIFICADAS São revelados sistemas e métodos para processar mensagens codificadas dentro de um sistema de comunicação sem fio. Um servidor dentro do sistema de comunicação sem fio efetua a verificação de assinatura de uma mensagem codificada e fornece, junto com a mensagem, uma indicação para o dispositivo móvel, de que a mensagem foi verificada. Além disso, o servidor fornece informação suplementar, como, por exemplo, um hash do certificado ou da cadeia de certificados utilizados para verificar a mensagem, para o dispositivo, para permitir que o dispositivo efetue verificações adicionais no certificado, como, por exemplo, verificações de validade, verificações de confiabilidade, verificações de pótencia, ou assemelhados.
