Abstract
Generally, this disclosure describes a system and method for trusted data processing in the public cloud. A system may include a cloud server including a trusted execution environment, the cloud server one of a plurality of cloud servers, a cloud storage device coupled to the cloud server, and a RKM server including a key server module, the RKM server configured to sign the key server module using a private key and a gateway server configured to provide the signed key server module to the cloud server, the trusted execution environment configured to verify the key server module using a public key related to the private key and to launch the key server module, the key server module configured to establish a secure communication channel between the gateway server and the key server module, and the gateway server configured to provide a cryptographic key to the key server module via the secure communication channel.
