Efficient Techniques for Privacy-Preserving Sharing of Sensitive Information [chapter]

Emiliano De Cristofaro, Yanbin Lu, Gene Tsudik
2011 Lecture Notes in Computer Science  
This poses two challenges: (1) how to enable this type of sharing such that parties learn no information beyond what they are entitled to, and (2) how to do so efficiently, in real-world practical terms  ...  A typical setting involves two parties: one seeks information from the other without revealing the interest while the latter is either willing, or compelled, to share only the requested information.  ...  Private Set Intersection (PSI) Private Set Intersection (PSI) [26] constitutes our main building block.  ...

Secure Multiparty Computation and Trusted Hardware: Examining Adoption Challenges and Opportunities

Joseph I. Choi, Kevin R. B. Butler
2019 Security and Communication Networks  
This paper revisits the history of improvements to SMC over the years and considers the possibility of coupling trusted hardware with SMC.  ...  Trusted execution environments (TEEs) provide hardware-enforced isolation of code and data in use, making them promising candidates for making SMC more tractable.  ...  Acknowledgments Special thanks are due to Patrick Traynor and Thomas Shrimpton for their interest in and constructive criticisms of this work.  ...

Untangling Blockchain: A Data Processing View of Blockchain Systems [article]

Tien Tuan Anh Dinh, Rui Liu, Meihui Zhang, Gang Chen, Beng Chin Ooi, Ji Wang
2017 arXiv   pre-print
Blockchains are distributed ledgers that enable parties who do not fully trust each other to maintain a set of global states. The parties agree on the existence, values and histories of the states.  ...  In this paper, we first survey the state of the art, focusing on private blockchains (in which parties are authenticated).  ...  Corda's consensus protocol is executed by a set of trusted parties called notaries which check if a given transaction has been executed before.  ...

image of a random value along with an encrypted version that is signed by the hardware to indicate that these values are properly produced.  ...  In this paper, we examine one such protocol and explore the consequences of replacing the statistical trust gained from cut-and-choose with a level of trust that depends on the use of secure, trusted hardware  ...  We believe that this is indeed possible, and could provide results quite similar to Katz's results but using our standard hardware components rather than custom-designed hardware tokens.  ...
