A Google anunciou o in\u00edcio do uso de chips baseados na plataforma aberta OpenTitan em dispositivos Chromebook. Os Chromebooks se tornaram os primeiros dispositivos comercialmente dispon\u00edveis com OpenTitan. Este ano, os data centers da Google planejam come\u00e7ar a implementar sistemas de servidores com OpenTitan. A produ\u00e7\u00e3o em massa dos chips est\u00e1 a cargo da Nuvoton. Al\u00e9m disso, foi mencionado o in\u00edcio do trabalho na segunda vers\u00e3o do chip, que permitir\u00e1 o uso de algoritmos de criptografia p\u00f3s-qu\u00e2nticos ML-DSA e ML-KEM para inicializa\u00e7\u00e3o segura e atesta\u00e7\u00e3o, implementando m\u00e9todos de criptografia baseados na solu\u00e7\u00e3o de problemas da teoria de redes.

\"A<\/center> <\/p>\n

O projeto OpenTitan fornece uma plataforma para a cria\u00e7\u00e3o de componentes de hardware confi\u00e1veis (RoT, Root of Trust), utilizados onde \u00e9 necess\u00e1rio garantir a integridade dos elementos de hardware e software do sistema. O OpenTitan foi fundado pela Google em 2018, mas em 2019 foi transferido para a organiza\u00e7\u00e3o sem fins lucrativos lowRISC, ap\u00f3s o que empresas como Western Digital, Seagate, Nuvoton Technology, Winbond, Rivos, zeroRISC e G+D Mobile Security se juntaram ao seu desenvolvimento. O c\u00f3digo e as especifica\u00e7\u00f5es dos componentes de hardware relacionados ao projeto foram publicados sob a licen\u00e7a Apache 2.0. As solu\u00e7\u00f5es aplicadas no OpenTitan s\u00e3o baseadas em tecnologias j\u00e1 utilizadas em tokens USB criptogr\u00e1ficos Google Titan e chips TPM para garantir uma inicializa\u00e7\u00e3o verificada, instalados na servidores<\/a> infraestrutura da Google, bem como em dispositivos Chromebook e Pixel. <\/p>\n

Ao contr\u00e1rio das implementa\u00e7\u00f5es existentes do Root of Trust, o OpenTitan est\u00e1 em desenvolvimento de acordo com o conceito de \"seguran\u00e7a por meio da transpar\u00eancia\", que implica na disponibilidade do c\u00f3digo e dos esquemas, al\u00e9m da aplica\u00e7\u00e3o de um processo de desenvolvimento totalmente aberto, n\u00e3o vinculado a fornecedores ou fabricantes de chips espec\u00edficos. O OpenTitan tornou-se a primeira implementa\u00e7\u00e3o do Root of Trust aberta no mercado, que suporta um mecanismo de inicializa\u00e7\u00e3o segura p\u00f3s-qu\u00e2ntica, baseado no uso do algoritmo de assinatura digital SLH-DSA (Sphincs+), resistente \u00e0 quebra por computadores qu\u00e2nticos. <\/p>\n

Os chips baseados em OpenTitan podem ser usados em placas-m\u00e3e de servidores, placas de rede, dispositivos consumidores, roteadores e dispositivos de Internet das Coisas para verificar firmwares e componentes carregados (prote\u00e7\u00e3o contra modifica\u00e7\u00e3o de partes cr\u00edticas do sistema), para gerar identificadores de sistema criptograficamente \u00fanicos (prote\u00e7\u00e3o contra substitui\u00e7\u00e3o de hardware), para fornecer servi\u00e7os de seguran\u00e7a, para proteger chaves criptogr\u00e1ficas (isolamento de chaves em caso de acesso f\u00edsico n\u00e3o autorizado ao hardware) e para manter um log de auditoria isolado, que n\u00e3o pode ser editado ou apagado. <\/p>\n

OpenTitan inclui blocos l\u00f3gicos demandados em chips RoT, como um microprocessador aberto baseado na arquitetura RISC-V (RV32IMCB Ibex), coprocessadores criptogr\u00e1ficos, um gerador de n\u00fameros aleat\u00f3rios de hardware, um gerenciador de chaves com suporte a DICE, um mecanismo de armazenamento seguro de dados na mem\u00f3ria persistente e vol\u00e1til, tecnologias de prote\u00e7\u00e3o, blocos de entrada\/sa\u00edda e componentes de boot seguro. O dispositivo tamb\u00e9m fornece blocos com a implementa\u00e7\u00e3o de algoritmos de criptografia padr\u00e3o, como AES e HMAC-SHA256, e um acelerador de opera\u00e7\u00f5es matem\u00e1ticas aplicadas em algoritmos para trabalhar com assinaturas digitais baseadas em chaves p\u00fablicas. <\/p>\n
