Abstract
The present disclosure provides a remote host monitoring method based on chip-level privacy-preserving computation (PPC), including: S1: allowing monitoring software in a user-side host to start in a chip-level trusted execution environment (TEE); S2: determining whether the user-side host locally stores valid private data, directly going to step S4 if yes, or otherwise, going to step S3; S3: establishing a secure connection with a supervisor and capturing private data; and S4: allowing monitoring software running in the TEE to execute a related monitoring instruction based on the private data, encrypting and signing a monitoring result, and transmitting the monitoring result to the supervisor. The present disclosure ensures validity, tamper resistance and security of monitoring information of the user with a TEE based on PCC, encrypts and signs the monitoring information based on an encryption key and a signature key of the supervisor, can locally store the monitoring information.
