Abstract
One embodiment of the present invention provides a system to facilitate collaboration for mitigating network threats. During operation, the system receives encrypted data sets from a plurality of entities. The data sets including data describing threats to network security. The system performs privacy-preserving operations on the encrypted data sets, such as private set intersection. The system then computes one or more metrics based on results of the private set intersection computations. The system may generate a similarity matrix based on the one or more metrics, and returns one or more similarity values from the similarity matrix to one or more entities of the plurality of entities.
