Embodiments disclosed herein describe computing private set intersection (PSI) between various parties using delegation to other devices and in one round of interaction (request and response). The various parties involved and their associated computing devices are referred to herein as participants. The protocol is forward-secure and completely hides the data of participants from an eavesdropper. Because the protocol only uses a single round of interaction, it is more efficient and does not require each participant to have servers that remain online continuously.

Delegated private set intersection, and applications thereof

Embodiments disclosed herein describe computing calculations based on two overlapping private sets between various parties. To conduct the calculation, an intersection of the overlapping private sets data lists is conducted without revealing the underlying data. A homomorphic encryption is conducted on the intersecting data elements to allow them to be compared.
