Abstract

MéTODO PARA AUTENTICAçãO E EXECUçãO DE UM PROGRAMA. Ao contrário da tecnologia para um programa baixado através de ondas de difusão convencionais, no caso de download de um programa através de uma rede, há uma possibilidade de que esse programa será ativado sem notificação de que o programa é falsificado. Por essa razão, quando um programa é baixado através de uma rede, uma hierarquia de arquivos para o programa localizado em um servidor é construída em uma área local de um terminal. Subseqüentemente, a autenticação do programa é realizada com relação á hierarquia de arquivos construída na área local e a credibilidade do programa é garantida.
