The researchers’ proposed Secure Data Exchange (SDE) protocol is based on the principles of the secure multi-party computation approach to cryptography. Its design allows third parties to carry out computations on encrypted, cloud-stored data and share their results.
“None of the parties will learn anything about the data beyond what they already know and what will be revealed by the function output,” a research paper authored by the group states.
“The data stored in the cloud can be used repeatedly for an arbitrary number of interactions.”
