CS&E Colloquium: Disclosure Control for Network Measurements

Abstract

How do we ensure that sharing network measurements does not disclose information that should not be disclosed? Today's approaches to this problem rely on best effort and, ultimately, trusting that network data is not misused. This talk explores a different technical approach that involves sound, machine-checked guarantees around non-disclosure. The talk introduces an eBPF-based approach to encode disclosure policies and presents the design, implementation, and evaluation of a general—yet disclosure-controlled—approach to carry out flexible measurements over packet streams. The talk also reports on an early deployment experience of this approach that builds on the Patchwork project.
