【Abstract】With the increasingly stringent regulatory requirements for data security all around the world, advanced privacy preserving data protection strategies and corresponding secure computation protocols are in urgent needs. The traditional methods for original data transaction and processing may conflict with the data regulation and laws. Thus, the object of data transaction nowadays is no longer the original data, but the encapsulated data services, which seal and combine various computing models and protocols that operate on local data. This paper concludes the cryptography based secure computation protocols including proxy re-encryption (PRE), multiparty computation (MPC), and zero-knowledge proof protocol (ZK), then organizes these protocols into smart contract-based layers on blockchain to support verifiable credentials and presentations, authorization-based data re-encryption, and MPC-based data secure computation as well as aggregations with ZK property.
