Secure Stable Matching at Scale

Jack Doerner, David Evans, abhi shelat
2016 Proceedings of the 2016 ACM SIGSAC Conference on Computer and Communications Security - CCS'16  
When a group of individuals and organizations wish to compute a stable matching-for example, when medical students are matched to medical residency programs-they often outsource the computation to a trusted arbiter in order to preserve the privacy of participants' preferences. Secure multi-party computation offers the possibility of private matching processes that do not rely on any common trusted third party. However, stable matching algorithms have previously been considered infeasible for

We adapt the classic Gale-Shapley algorithm for use in such a context, and show experimentally that our modifications yield a lower asymptotic complexity and more than an order of magnitude in practical cost improvement over previous techniques. Our main improvements stem from designing new oblivious data structures that exploit the properties of the matching algorithms. We apply a similar strategy to scale the Roth-Peranson instability chaining algorithm, currently in use by the National Resident Matching Program. The resulting protocol is efficient enough to be useful at the scale required for matching medical residents nationwide, taking just over 18 hours to complete an execution simulating the 2016 national resident match with more than 35,000 participants and 30,000 residency slots.

Privacy-Preserving Distributed Linear Regression on High-Dimensional Data

Adrià Gascón, Phillipp Schoppmann, Borja Balle, Mariana Raykova, Jack Doerner, Samee Zahur, David Evans
2017 Proceedings on Privacy Enhancing Technologies  
We propose privacy-preserving protocols for computing linear regression models, in the setting where the training dataset is vertically distributed among several parties. Our main contribution is a hybrid multi-party computation protocol that combines Yao's garbled circuits with tailored protocols for computing inner products. Like many machine learning tasks, building a linear regression model involves solving a system of linear equations. We conduct a comprehensive evaluation and comparison

This algorithm is suitable for secure computation because it uses an efficient fixed-point representation of real numbers while maintaining accuracy and convergence rates comparable to what can be obtained with a classical solution using floating point numbers. Our technique improves on Nikolaenko et al.'s method for privacy-preserving ridge regression (S&P 2013), and can be used as a building block in other analyses. We implement a complete system and demonstrate that our approach is highly scalable, solving data analysis problems with one million records and one hundred features in less than one hour of total running time.

Cigarette Smoke Decreases Innate Responses of Epithelial Cells to Rhinovirus Infection

Jane Eddleston, Rachel U. Lee, Astrid M. Doerner, Jack Herschbach, Bruce L. Zuraw
2011 American Journal of Respiratory Cell and Molecular Biology  
Exposure to cigarette smoke is associated with a significant increase in the risk for respiratory viral infections. The airway epithelium is the primary target for both cigarette smoke and respiratory viral infection. We investigated the effects of cigarette smoke on the response of airway epithelial cells to rhinovirus infection. We found that pre-exposure of BEAS-2B cells or primary normal human bronchial epithelial cells (NHBEs) to cigarette smoke extract (CSE) reduced the induction of mRNA

The HRV-16-induced release of CXCL10 and CCL5 was also significantly suppressed by CSE. Activation of the IFN mediator STAT-1 and the activation of JNK by poly I:C and HRV-16 were partially suppressed by pre-exposure to CSE. In contrast, the poly I:C-induced and HRV-16-induced phosphorylation of ERK1/2 was unaffected by CSE. HRV-16-stimulated IFN-b mRNA was also significantly reduced by CSE. Because suppression of the IFN response to viral infection was associated with increased viral production, we assessed HRV-16 RNA concentrations. Exposure to CSE resulted in an increase in HRV-16 RNA at 48 hours after the infection of BEAS-2B cells. These data demonstrate that exposure to CSE alters the response of airway epithelial cells to HRV infection, leading to decreased activation of the IFN-STAT-1 and SAP-JNK pathways, the suppression of CXCL10 and CCL5 production, and increased viral RNA. A diminished, early epithelial-initiated antiviral response to rhinovirus infection could contribute to the increased susceptibility of subjects to prolonged respiratory viral infections after exposure to cigarette smoke.
