Abstract

----------------------- page 1----------------------- 1/1 resumo mã‰todo para proteger de conteãšdo usando chaves especã�ficas de domã�nio diferentes um mã©todo operacional dentro de um controlador de memã³ria ã© fornecido para proteger do conteãºdo armazenado na memã³ria. o controlador de memã³ria pode alocar regiãµes de memã³ria lã³gica dentro de um dispositivo de memã³ria para diferentes domã­nios. uma chave especã­fica de domã­nio diferente para cada um dos domã­nios diferentes, onde cada chave especã­fica de domã­nio ã© uma funã§ã£o de pelo menos uma chave mestre e informaã§ãµes especã­ficas de domã­nio. durante as operaã§ãµes de escrita (gravaã§ã£o), o conteãºdo/dados ã© criptografado, no controlador de memã³ria, na medida em que ã© gravado em cada regiã£o de memã³ria lã³gica usando uma chave especã­fica de domã­nio correspondente a um domã­nio que fornece o conteãºdo e ao qual a regiã£o de memã³ria lã³gica estã¡ alocada. de modo similar, durante as operaã§ãµes de leitura, o conteãºdo/dados sã£o desencriptados, no controlador de memã³ria, na medida em que sã£o lidos a partir de cada regiã£o de memã³ria lã³gica usando uma chave especã­fica de domã­nio correspondente a um domã­nio que solicita o conteãºdo e ao qual a regiã£o de memã³ria lã³gica, onde o conteãºdo ã© armazenado, estã¡ alocada.
