Compile Header Attestation For Free

The attestation process uses a series of measurements that are unique to an enclave. You can use these measurements to create access policies in external services to grant the enclave access to special cryptographic operations.

Attestation Date: Defines the date on which the attestation task was initiated, and the point in time with respect to the attestation data that the user must attest to. Note that the reviewer does not attest to what the user has today. They attest to what the user had on the date specified in the attestation task.

Attestation is the act of witnessing the signing of a formal document and then also signing it to verify that it was properly signed by those bound by its contents. Attestation is a legal acknowledgment of the authenticity of a document and a verification that proper processes were followed.

Generally speaking, attestation is designed to prove a property of a system to a third party. In the case of confidential computing, this generally means a proof that the execution environment can be trusted before starting to execute code or before delivering any secret information.

The initial attestation service creates a that contains a fixed set of device-specific data, upon request. To sign the , the device must contain an attestation key pair, which is unique per device.

Key attestation verifies the extension data that appears in the first certificate within the chain in a device's hardware-backed keystore.

SafetyNet's attestation API verify the device's status against various factors (as per Google) like unlocked bootloader, presence of root binaries or third-party firmware (custom ROMs), and more.

You make the declarations in a header file, then use the #include directive in every . cpp file or other header file that requires that declaration. The #include directive inserts a copy of the header file directly into the . cpp file prior to compilation.

Only source files are passed to the compiler (to preprocess and compile it). Header files aren't passed to the compiler. Instead, they are included from source files.

A header file is a file with extension . h which contains C function declarations and macro definitions to be shared between several source files. There are two types of header files: the files that the programmer writes and the files that comes with your compiler.
