In thetrusted data-element circulation system, which technology combination is generally used formedium-confidentiality data circulation?

For medium-confidentiality data, privacy and security must be ensured.Ciphertextprotects data in storage and transmission, andMPC (Multi-Party Computation)enables joint computation without revealing raw data, making it suitable for this scenario. Plaintext transmission is too risky; federated learning focuses on model training rather than direct circulation of original data.
