Differential Secrecy for Distributed Data and Applications to Robust Differentially Secure Vector Summation

Authors: Kunal Talwar

Published in: LIPIcs, Volume 218, 3rd Symposium on Foundations of Responsible Computing (FORC 2022)


Abstract
Computing the noisy sum of real-valued vectors is an important primitive in differentially private learning and statistics. In private federated learning applications, these vectors are held by client devices, leading to a distributed summation problem. Standard Secure Multiparty Computation protocols for this problem are susceptible to poisoning attacks, where a client may have a large influence on the sum, without being detected. In this work, we propose a poisoning-robust private summation protocol in the multiple-server setting, recently studied in PRIO [Henry Corrigan-Gibbs and Dan Boneh, 2017]. We present a protocol for vector summation that verifies that the Euclidean norm of each contribution is approximately bounded. We show that by relaxing the security constraint in SMC to a differential privacy like guarantee, one can improve over PRIO in terms of communication requirements as well as the client-side computation. Unlike SMC algorithms that inevitably cast integers to elements of a large finite field, our algorithms work over integers/reals, which may allow for additional efficiencies.

Authors: Dan Boneh, Ulfar Erlingsson, Martin Johns, and Benjamin Livshits

Published in: Dagstuhl Seminar Proceedings, Volume 9141, Web Application Security (2010)


Abstract
From 29th March to 3rd April 2009 the Dagstuhl Seminar 09141 Web Application Security was held in Schloss Dagstuhl – Leibniz Center for Informatics. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar are put together in this paper. Links to full papers (if available) are provided in the corresponding seminar summary document.

09141 Executive Summary – Web Application Security

Authors: Dan Boneh, Ulfar Erlingsson, Martin Johns, and Benjamin Livshits

Published in: Dagstuhl Seminar Proceedings, Volume 9141, Web Application Security (2010)


Abstract
Web applications are ubiquitous nowadays. Consequently, the field of Web application security is of ever rising significance. This Dagstuhl seminar was conducted to assemble researchers active in the domain to gain a first comprehensive overview of this young discipline in security research. From a content perspective, the topic was explored in a great variety of directions, including for instance Web browser-based security measures, language-based techniques, software engineering centric methods, run-time enforcement, static analysis, or formal approaches.
