Privacy-Safe Network Trace Sharing via Secure Queries


Problem Statement

Contemporary network researches are difficult, because


Our solution: Privacy-safe network trace sharing framework, with privacy and security in mind via Trol and Patrol.

Patrol is designed to solve the problems mentioned above. It provides a framework that securely stores traces and provide a query interface for users, and return results that are fine-tuned to avoid leaking sensitive data, while still with enough statistical information for research purposes. Queries are expressed in an SQL-like language, Trol, that supports most common trace processing primitives.

Trol overview


Trol/Patrol are in active development, and our source code will be publicly available soon.
