A principal função do documento de atestação é fornecer uma garantia criptográfica de que um determinado enclave foi inicializado em um estado seguro e está executando um software específico. Ele pode incluir informações como:

No entanto, essas informações são geralmente insuficientes para reproduzir o "estado interno" do enclave, que incluiria coisas como:

PCR | Hash of ... | Description -- | -- | -- PCR0 | Enclave image file | A contiguous measure of the contents of the image file, without the section data. PCR1 | Linux kernel and bootstrap | A contiguous measurement of the kernel and boot ramfs data. PCR2 | Application | A contiguous, in-order measurement of the user applications, without the boot ramfs. PCR3 | IAM role assigned to the parent instance | A contiguous measurement of the IAM role assigned to the parent instance. Ensures that the attestation process succeeds only when the parent instance has the correct IAM role. PCR4 | Instance ID of the parent instance | A contiguous measurement of the ID of the parent instance. Ensures that the attestation process succeeds only when the parent instance has a specific instance ID. PCR8 | Enclave image file signing certificate | A measure of the signing certificate specified for the enclave image file. Ensures that the attestation process succeeds only when the enclave was booted from an enclave image file signed by a specific certificate.

Which instance types are supported?

Nitro Enclaves is currently supported on the majority of Graviton, Intel, and AMD-based Amazon EC2 instance types built on the AWS Nitro System. Nitro Enclaves is not currently available on bare metal instances, burstable instance types (e.g. T3), and instances with only 1 CPU core.
