\nPlaca gr\u00e1fica Intel Xe com suporte a GPU SGX<\/i><\/p>\n

Desde o momento em que foi anunciado que a Intel desenvolveria sua placa de v\u00eddeo discreta, toda a humanidade progressista aguarda o momento em que os planos come\u00e7ar\u00e3o a se transformar em algo material. Poucos detalhes t\u00e9cnicos s\u00e3o conhecidos at\u00e9 agora, mas hoje podemos compartilhar algo espec\u00edfico e, al\u00e9m disso, importante. Foi revelado que a futura placa de v\u00eddeo Intel suportar\u00e1 uma tecnologia an\u00e1loga a Intel SGX<\/a><\/noindex>, para armazenamento super confi\u00e1vel de conte\u00fado extremamente importante - ela se chama GPU SGX.
\n<\/a><\/noindex>
\nRecentemente, mencionamos a tecnologia Intel Software Guard Extensions em rela\u00e7\u00e3o a o lan\u00e7amento da Intel SGX Card<\/a><\/noindex>. As extens\u00f5es Intel SGX s\u00e3o um conjunto de instru\u00e7\u00f5es da CPU que permitem que os aplicativos criem enclaves, \u00e1reas protegidas no espa\u00e7o de endere\u00e7os do aplicativo, garantindo a privacidade e a integridade mesmo na presen\u00e7a de malware com privil\u00e9gios elevados. <\/p>\n

Mas \u00e9 preciso proteger n\u00e3o apenas o c\u00f3digo em execu\u00e7\u00e3o, mas tamb\u00e9m os dados dos usu\u00e1rios. Legi\u00f5es de criminosos sonham dia e noite em roubar suas fotos e depois apag\u00e1-las ou criptograf\u00e1-las. Como n\u00e3o ficar sem as mem\u00f3rias mais importantes? Aqui, o Intel SGX tamb\u00e9m pode ajudar, em sua variante GPU SGX. Nesse caso, ela funciona da seguinte forma.<\/p>\n

\"Intel
\n
\nO papel crucial nesta tecnologia, como o nome sugere, \u00e9 desempenhado pela unidade de processamento gr\u00e1fico. \"Qual \u00e9 a rela\u00e7\u00e3o da placa de v\u00eddeo com o armazenamento de dados?\" - voc\u00ea deve perguntar. O fato \u00e9 que, apesar de todo o respeito pelo Intel SGX, o n\u00famero de processadores que suportam essa tecnologia \u00e9 significativamente menor do que aqueles que n\u00e3o suportam. Portanto, foi tomada a decis\u00e3o de transferir a execu\u00e7\u00e3o do c\u00f3digo dependente do SGX para a GPU, de forma an\u00e1loga ao que foi feito na j\u00e1 mencionada Intel SGX Card. A placa de v\u00eddeo tamb\u00e9m possui outra vantagem: sua estrutura permite acomodar uma quantidade consider\u00e1vel de mem\u00f3ria flash, que pode ser usada como armazenamento protegido local.<\/p>\n

O princ\u00edpio de funcionamento do GPU SGX \u00e9 o seguinte. Fotos do seu cachorro favorito, assim como outros dados especialmente importantes, s\u00e3o armazenados no armazenamento local da placa gr\u00e1fica com a ajuda de um software especial da Intel. A prote\u00e7\u00e3o Intel SGX opera no n\u00edvel do driver do sistema de arquivos. Em seguida, o mesmo software especial sincroniza o conte\u00fado do armazenamento com um servi\u00e7o em nuvem em um dos modos escolhidos pelo usu\u00e1rio. Ao contr\u00e1rio de outros servi\u00e7os em nuvem, o cliente Intel n\u00e3o pode ser comprometido, pois ele armazena \u00e1reas sens\u00edveis de c\u00f3digo em enclaves SGX. Assim, seus dados recebem v\u00e1rias camadas de prote\u00e7\u00e3o contra roubo e destrui\u00e7\u00e3o.<\/p>\n

E o que acontece se o software da Intel parar de funcionar por algum motivo e os dados ficarem literalmente trancados em seu armazenamento? A Intel pretende compartilhar sua tecnologia com terceiros com base em uma certifica\u00e7\u00e3o e controle rigorosos. Portanto, haver\u00e1 uma alternativa. A pr\u00f3pria sistema n\u00e3o estar\u00e1 dispon\u00edvel no mercado antes do lan\u00e7amento das placas gr\u00e1ficas \u2014 o prazo ainda \u00e9 incerto. Mas estaremos aguardando.
