NRA-POC: Empirical Measurements for a Stateless Tor-Based Secure Communication System

Empirical measurement data for NRA-POC, a stateless Tor-based secure communication system designed for legal professionals. The dataset contains results from four measurement campaigns covering metadata entropy, communication graph reconstructability, session artifact purge timing, and Perfect Forward Secrecy effectiveness. It is a companion dataset to a manuscript submitted to the Journal of Information Security and Applications (JISA) and was authored by Tomasz Janczewski.

Use Cases

• Benchmarking metadata entropy in anonymous networks based on the Shannon metadata entropy measurements
• Evaluating communication graph reconstructability for privacy analysis based on the Monte Carlo simulation results
• Analyzing the performance of cryptographic artifact purging based on the session artifact purge timing data
• Validating Perfect Forward Secrecy implementation effectiveness based on the 100% success rate across sessions

Strengths

• Provides specific quantitative results, including a mean metadata entropy of 1.90 ± 0.17 bits/event
• Includes a comparative baseline showing a 31.2% reduction in graph reconstructability versus a static system
• Reports precise timing measurements for different purge operations (e.g., 12.30 ms for files with secure delete)

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
