SYSTEMS AND METHODS FOR SECURE AND FAST MACHINE LEARNING INFERENCE IN TRUSTED EXECUTION ENVIRONMENT

WIPO Patent Application WO/2022/073264

A1

A method for executing a machine learning (ML) application in a computing environment includes receiving a secret from a trusted execution environment (TEE) of a user computing device into a TEE of a server. The user computing device is authenticated by an identity and access management service. The TEE validates the secret against a time-limited token. The method further receives from a TEE of a model release tool a model encryption key bound to the ML application. The method receives into the TEE of the server, an ML model of the ML applications encrypted with the MEK. The method decrypts using the MEK the ML model. The method receives into the TEE of the server the ML application and a descriptor of the ML application encrypted by a cryptographic key derived from the secret. The method executes the ML application using the ML model and the descriptor.
