DiStefano: A Secure Framework for Sharing Encrypted Web Traffic Facts
DiStefano is a secure and efficient framework designed to generate private commitments about web traffic encrypted with TLS 1.3, allowing verification by designated third parties. This innovative system protects against malicious attacks while maintaining user privacy.
Key Features:
- Modular protocol specifically designed for TLS 1.3
- Support for verifiable claims about encrypted data
- Built-in ring privacy protection for browsing history
- Optimized performance for TLS 1.3 sessions
The framework has been implemented as open-source software and integrated into BoringSSL, the cryptographic library used by Chromium-based browsers. Performance testing in a LAN environment shows DiStefano requires:
- Less than 1 second execution time
- 5KB or less data transfer
- Minimal computational overhead
DiStefano represents a significant improvement over existing TLS commitment systems through its enhanced security features and efficient operation. The system enables reliable encrypted fact-sharing while maintaining strict privacy controls.
Technical Implementation:
- Built on BoringSSL cryptographic library
- Permissive open-source licensing
- Compatible with current web infrastructure
- Designed for practical deployment at scale
Primary authors include researchers from:
- Brave Software
- NOVA University of Lisbon
- Imperial College London
- Royal Holloway, University of London
- Hashmatter
This innovative framework establishes a new standard for secure, private, and verifiable web traffic commitments while maintaining high performance and practicality for real-world applications.
