OpenSSL RSA Performance and Energy Benchmarking

This repository contains a benchmarking script designed to measure the performance and energy consumption of RSA-2048 operations using OpenSSL. The script supports multi-threaded execution and leverages Intel RAPL for precise energy measurements on compatible systems.

Features

• Automatic detection of logical CPU cores
• RSA-2048 benchmarking using openssl speed with multiple threads
• Execution time, average power (W), and total energy consumption (J) measurement via Intel RAPL
• Results exported to CSV format
• Python script for result analysis and visualization

Requirements

System

• bash
• openssl CLI
• bc (for floating-point math)
• Intel RAPL support via /sys/class/powercap/intel-rapl:0 (optional but recommended)

Python 3.8+

Install Python dependencies with:

pip install -r requirements.txt

Usage Make the benchmark script executable:

chmod +x openssl_speed_server.sh

Run the benchmark:

./openssl_speed_server.sh

Results will be stored in:

./openssl_speed_results/openssl_speed_results.csv

Analyze and visualize the results with:

parse_results.py

Notes Energy consumption data is only available if the system exposes Intel RAPL to userspace.
