Abstract

<B>MéTODO PARA PRODUZIR SAìDA UTILIZANDO FUNçãO PSEUDO-ALEATóRIA<D> Os dados que indicam o uso de uma saída de função pseudo-aleatória são utilizados para modificar pelo menos um valor utilizado para produzir a saída de função pseudo-aleatória. Em uma modalidade, os sinais de controle de saída fornecidos para um Módulo de Identidade de Usuário (UIM) são utilizados como entradas para um processador de função pseudo-aleatória. Como resultado, a saída fornecida pelo processador difere com base em se a saída do processador deve ser armazenada em uma área de armazenagem de chave ou se deve ser exportada para uso fora do UIM. Esta técnica resolve o problema da técnica anterior, assegurando que os valores que são exportados ou apresentados na saída do módulo UIM sejam diferentes dos valores armazenados no módulo UIM como valores de chave. Como resultado, um agressor receberia valores na saída do UIM diferentes daqueles armazenados na unidade de armazenagem de chave e, portanto, não seria capaz de representar o terminal móvel ou comprometer a privacidade das comunicações do terminal.
