A empresa Google apresentou<\/a><\/noindex> novo projeto aberto OpenTitan<\/a><\/noindex>, que \u00e9 uma plataforma para a cria\u00e7\u00e3o de componentes de hardware confi\u00e1veis (RoT, Root of Trust). O OpenTitan \u00e9 baseado em tecnologias j\u00e1 utilizadas em tokens USB criptogr\u00e1ficos Google Titan<\/a><\/noindex> e chips TPM<\/a><\/noindex> para garantir o boot verificado, instalados em servidores na infraestrutura do Google, assim como em dispositivos Chromebook e Pixel. O c\u00f3digo e as especifica\u00e7\u00f5es relacionadas ao projeto foram publicados<\/a><\/noindex> est\u00e3o no GitHub sob a licen\u00e7a Apache 2.0.<\/p>\n

Ao contr\u00e1rio das implementa\u00e7\u00f5es existentes do Root of Trust, o novo projeto se desenvolve de acordo com o conceito de \"seguran\u00e7a atrav\u00e9s da transpar\u00eancia\", que implica um processo de desenvolvimento totalmente aberto e a acessibilidade do c\u00f3digo e dos esquemas. O OpenTitan pode ser utilizado como uma estrutura pronta, testada e confi\u00e1vel, permitindo aumentar a confian\u00e7a nas solu\u00e7\u00f5es criadas e reduzir os custos no desenvolvimento de chips especializados para seguran\u00e7a. O OpenTitan ser\u00e1 desenvolvido em uma plataforma independente como um projeto colaborativo, n\u00e3o vinculado a fornecedores e fabricantes de chips espec\u00edficos. <\/p>\n

O desenvolvimento do OpenTitan ser\u00e1 supervisionado por uma organiza\u00e7\u00e3o sem fins lucrativos lowRISC<\/a><\/noindex>, que desenvolve um microprocessador livre baseado na arquitetura RISC-V. J\u00e1 se juntaram ao trabalho conjunto no OpenTitan as empresas G+D Mobile Security, Nuvoton Technology e Western Digital, assim como a ETH Zurich e a Universidade de Cambridge, cujos pesquisadores desenvolvem uma arquitetura de processador segura CHERI<\/a><\/noindex> (Capability Hardware Enhanced RISC Instructions) e recentemente recebeu<\/a><\/noindex> recebeu uma concess\u00e3o de 190 milh\u00f5es de euros para adaptar as tecnologias relacionadas para processadores ARM e criar um prot\u00f3tipo de uma nova plataforma de hardware Morello.<\/p>\n

O projeto OpenTitan abrange o desenvolvimento de diversos componentes l\u00f3gicos, requisitados em chips RoT, incluindo um microprocessador aberto lowRISC Ibex<\/a><\/noindex> Baseado na arquitetura RISC-V, coprocessadores criptogr\u00e1ficos, gerador de n\u00fameros aleat\u00f3rios em hardware, hierarquia de armazenamento de chaves e dados em mem\u00f3ria permanente e RAM, mecanismos de prote\u00e7\u00e3o, blocos de entrada\/sa\u00edda, meios de inicializa\u00e7\u00e3o segura, etc. OpenTitan pode ser aplicado onde \u00e9 necess\u00e1rio garantir a integridade dos componentes de hardware e software do sistema, certificando-se de que os componentes cr\u00edticos do sistema n\u00e3o foram substitu\u00eddos e se baseiam em c\u00f3digo verificado e autorizado pelo fabricante. <\/p>\n

Os chips baseados em OpenTitan podem ser usados em
\nplacas-m\u00e3e de servidores, placas de rede, dispositivos de consumo, roteadores, dispositivos de Internet das Coisas para verifica\u00e7\u00e3o de firmware (detec\u00e7\u00e3o de modifica\u00e7\u00f5es por malware), fornecimento de um identificador de sistema criptograficamente \u00fanico (prote\u00e7\u00e3o contra substitui\u00e7\u00e3o de hardware), prote\u00e7\u00e3o de chaves criptogr\u00e1ficas (isolamento de chaves em caso de acesso f\u00edsico malicioso ao hardware), fornecimento de servi\u00e7os relacionados \u00e0 seguran\u00e7a e manuten\u00e7\u00e3o de um registro de auditoria isolado que n\u00e3o pode ser editado ou apagado.<\/p>\n
