An Oblivious Transfer Protocol with Log-Squared Communication
Abstract. We propose a one-round 1-out-of-n computationally-private information retrieval protocol for -bit strings with low-degree polylogarithmic receivercomputation, linear send...

Efficiency-Improved Fully Simulatable Adaptive OT under the DDH Assumption
At Asiacrypt 2009, Kurosawa and Nojima showed a fully simulatable adaptive oblivious transfer (OT) protocol under the DDH assumption in the standard model. However, Green and Hohen...

A Practical Privacy-Preserving Cooperative Computation Protocol without Oblivious Transfer for Linear Systems of Equations
: We propose several practical SMC protocols for privacy-preserving cooperative scientific computations. We consider two important scientific computations which involve linear equa...
