Anonymous Networks and Currencies

Anonymous networks and cryptocurrencies have many legitimate applications to support the freedom of the press, protect human rights, and allow new methods of payments that protect individual privacy. However, criminals are exploiting the protections built into the encryption and the promise of near anonymity.

Investigating anonymous networks and cryptocurrencies is resource-intensive and difficult, requiring significant man-hours to investigate and prosecute criminals involved in illegal activities on anonymous marketplaces and websites.

DHS S&T is developing cost-effective solutions for law enforcement (LE) components to complement and expand their capabilities to investigate crimes. Strong partnerships with LE results in requirements for solutions fitting specific investigative needs while protecting the privacy and the legitimate uses of anonymous networks and cryptocurrencies.

Current Anonymous Networks and Currencies Efforts

New Tor Service Protocol: DHS S&T is developing a new service protocol for The Onion Router (Tor) to provide stronger encryption and protections for law enforcement communications within the anonymous networks. This effort will improve security through protocol enhancements and provide end-to-end encryption.

Safe Aggregation of Usage Statistics: DHS S&T is developing techniques to provide for a safe aggregation of usage statistics within anonymous networks while respecting and protecting the privacy and anonymity of anonymous network users.

System Analysis, Requirements Gathering, and Tool Development: DHS S&T is developing working with the LE community to conduct a system analysis of the broader anonymous network and cryptocurrency landscape to generate additional requirements and develop broader solutions to investigate criminal activities.

Cryptocurrency Forensics: DHS S&T is developing tools to enable LE to perform forensic analysis of cryptocurrency transactions and facilitate the tracing of currencies involved in illicit transactions.
