摘要
A device, system and method for secure collaborations on encrypted data in a hybrid environment of a homomorphic encryption (HE) enabled device and trusted hardware. A set of computations may be divided into a subset of linear computations and a subset of non-linear computations. The linear computations on the encrypted data may be executed using homomorphic encryption (HE) in the homomorphic encryption (HE) enabled device. The non-linear computations on the unencrypted data may be executed in the trusted hardware in an unencrypted domain and encrypting the result. The results of the linear and non-linear computations may be decrypted and merged to generate a result equivalent to executing the set of linear and non-linear computations on the unencrypted data.
