摘要

An apparatus for sharing information between entities includes a processor and a trusted execution module executing on the processor. The trusted execution module is configured to receive first confidential information from a first client device associated with a first entity, seal the first confidential information within a trusted execution environment, receive second confidential information from a second client device associated with a second entity, seal the second confidential information within the trusted execution environment, and execute code within the trusted execution environment. The code is configured to compute a confidential result based upon the first confidential information and the second confidential information.
