+# GET_EAT Command
+
+## Overview
+
+The GET_EAT command enables verifiers to obtain attestation evidence from a device in the form of an Entity Attestation Token (EAT) that conforms to the OCP EAT Profile. This command is allocated in the [@{ocp-command-registry}] and is designed to be transport-agnostic while providing a standardized interface for attestation requests.
+
+## Command Definition
+
+The GET_EAT command is assigned command code 0x02 in the [@{ocp-command-registry}].
+

++---------------------+---------------------+---------------------+----------------------------------------------+
+
+**Note**: Error conditions are reported using transport-specific error mechanisms with error codes from [@{ocp-command-registry}].
+
+## EAT Token Requirements
+
+The EATToken returned in the GET_EAT response **MUST** conform to the OCP EAT Profile specification, which includes:
+
+1. The EAT **MUST** be encoded as a signed CWT (CBOR Web Token)
+2. The EAT Profile claim (265) **MUST** be present and contain the OCP Profile OID
+3. The Nonce claim (10) **MUST** be present and contain the exact nonce value from the request (matching both value and length)
+4. The Measurements claim (273) **MUST** be present and contain concise evidence as defined in the OCP EAT Profile
+5. The issuer claim (1) **MUST** be present to bind the EAT to the certificate chain that issued it
+6. The rim-locators claim (-70001) **MAY** be present to reference CoRIM locations
+
+**Note:** The nonce claim in the EAT response must preserve both the value and length of the nonce provided in the GET_EAT request to ensure proper freshness verification.
+
+## Transport Bindings
+
+### SPDM Binding
+
+When transported over SPDM, the GET_EAT command utilizes the VENDOR_DEFINED mechanism as specified in the [@{ocp-command-registry}].
+
+For SPDM binding:
+
+- The SignerSlotID field **MUST** correspond to SPDM certificate slot numbers
+
+For detailed SPDM transport binding requirements including:
+
+- VENDOR_DEFINED message structure
+- Success and error case handling
+- ExtendedErrorData usage
+- Command framing specifications
+
+Please refer to the [@{ocp-command-registry}] specification.
+
+### Native Transport Bindings
+
+TSM engines and other transport mechanisms **MAY** define their own bindings for the GET_EAT command, provided they:
+
+- Maintain semantic equivalence of request and response structures
+- Preserve all required fields and their meanings
+- Implement appropriate error reporting using transport-native mechanisms
+- Document any transport-specific adaptations
