Abstract

"MéTODO E APARELHO PARA TRANSMITIR SEGURAMENTE SINAIS DE FAIXA DISTRIBUìDA PARA O USO NA AUTENTICAçãO DE ESTAçãO MóVEL". São descritos um método e um aparelho para gerar e comunicar valores de provocação (challenge) aleatórios para estações móveis que não percam a imprevisibilidade de um número realmente aleatório mas possa ser simples e economicamente sincronizado com sistemas celulares. o método e aparelho atualizam um número binário que será usado nos processos de autenticação de sistema de telefonia celular, aplicando um primeiro algoritmo a uma pluralidade de bits mais significativos de um primeiro número binário para obter um segundo número binário; opera em uma pluralidade de bits menos significativos do primeiro número binário com um segundo algoritmo para obter um terceiro número binário, e aplicar um cifra de bloco à concatenação dos segundo e terceiro números para obter o número binário atualizado. Quando os bits mais significativos do número binário atualizado compreendem um número todo de zeros eles são substituídos pelos bits mais significativos da concatenação dos segundo e terceiro números.
