PROTECTION SCHEME FOR REMOTELY-STORED DATA

摘要

The present disclosure is directed to a protection scheme for remotely-stored data. A system may comprise, for example, at least one device including at least one virtual machine (VM) and a trusted execution environment (TEE). The TEE may include an encryption service to encrypt or decrypt data received from the at least one VM. In one embodiment, the at least one VM may include an encryption agent to interact with interfaces in the encryption service. For example, the encryption agent may register with the encryption service, at which time an encryption key corresponding to the at least one VM may be generated. After verifying the registration of the encryption agent, the encryption service may utilize the encryption key corresponding to the at least one VM to encrypt or decrypt data received from the encryption agent. The encryption service may then return the encrypted or decrypted data to the encryption agent.
