Abstract
An application may perform operations within a first secure enclave of a processing device. The application may provide secure monitoring data, such as secure heartbeat information. The monitoring data and an application identity may be verified at a second secure enclave of the processing device using local attestation operations. A remote attestation signature may be generated at the second secure enclave based on the monitoring data, the application identity, and a node private key. A monitoring message signature may be generated at the first secure enclave based on an application private key and a message payload that includes the monitoring data, the application identity, and the remote attestation signature. A monitoring message that includes the payload and monitoring message signature may be sent from the first secure enclave to a monitoring system, which may verify the message to detect unauthorized changes to the monitoring data or the application identity.
