Zusammenfassung:The subject disclosure is directed towards using trusted hardware to achieve secure data processing over a network. For a given set of data store operations, some operations are directed to sensitive data (e.g., encrypted data fields). These operations are compiled into a set of expressions invoking trusted hardware code configured to evaluate these expressions using corresponding data centric primitive programs. Because the trusted hardware is configured to maintain key data for encrypting/decrypting the sensitive data, the sensitive data is not accessible by an untrusted component while the sensitive data is decrypted.
