Enforcing Secure and Privacy-Preserving Information Brokering in Distributed Information Sharing

Privacy-Preserving Distributed Information Sharing

In many important applications, a collection of mutually distrustful parties must share information, without compromising their privacy. Currently, these applications are often performed by using some form of a trusted third party (TTP); this TTP receives all players’ inputs, computes the desired function, and returns the result. However, the level of trust that must be placed in such a TTP is ...

Distributed Privacy Preserving Information Sharing

In this paper, we address issues related to sharing information in a distributed system consisting of autonomous entities, each of which holds a private database. Semi-honest behavior has been widely adopted as the model for adversarial threats. However, it substantially underestimates the capability of adversaries in reality. In this paper, we consider a threat space containing more powerful a...

Privacy Preserving Information Sharing

On Privacy Protection in Distributed Information Sharing

We address issues related to sharing information in a distributed system consisting of autonomous entities, each of which holds a private database. Semi-honest behavior has been widely adopted as the model for adversarial threats in such system. However, this model substantially underestimates the capability of adversaries in reality, and thus is insufficient to be adopted in many real systems....
