Homo²rpheOS: Homomorphic Cryptography Framework for Real-World Applications

Homo²rpheOS (or Homo2rpheOS, pronounced Homomorph[e]OS)

Homo²rpheOS is a state-of-the-art open-source framework designed to facilitate the development, testing, and implementation of homomorphic encryption schemes. The project integrates the latest advancements in privacy-preserving technologies, providing a powerful toolkit for developers and researchers in the field of cryptography and secure computing.

Homo²rpheOS is an open-source framework leveraging cutting-edge homomorphic encryption (HE) techniques, designed to enable secure computation on encrypted data without decryption. By supporting Microsoft SEAL and providing tools for experimentation, development, and integration, Homo²rpheOS paves the way for privacy-preserving solutions across industries.

🚀 Key Features

• Native Homomorphic Encryption: Built on the robust Microsoft SEAL library, supporting BFV, BGV, and CKKS encryption schemes.
• Modular Framework: Easily integrate custom HE computations into existing workflows.
• Comprehensive Examples: Explore practical implementations, from simple polynomial operations to advanced performance benchmarks.
• Optimized for Alpine Linux: Lightweight and efficient, ideal for containerized environments or resource-constrained systems.

🌟 Why Use Homo²rpheOS?

In today's world, data security and privacy are paramount. Homo²rpheOS ensures sensitive information remains encrypted, even during computation, mitigating risks of data exposure in sectors like:

1. Finance

   • Example: Securely compute aggregated loan risk across multiple financial institutions without exposing individual client data.
   • Use case: Encrypted salary data analysis for employee pay equity studies, while maintaining strict confidentiality.

2. Healthcare

   • Example: Run predictive models on encrypted medical records to identify at-risk patients, ensuring compliance with privacy regulations like GDPR and HIPAA.
   • Use case: Conduct encrypted genomic data analysis for personalized medicine, preserving patient anonymity.

📚 How It Works

1. Encryption of Sensitive Data

   • Input data is encrypted using chosen schemes (BFV, BGV, or CKKS).
   • The framework uses polynomial operations (e.g., multiplication, addition) to compute on ciphertexts.

2. Secure Computations

   • Homomorphic operations allow secure calculations without decrypting data.
   • The noise budget is actively managed to ensure accuracy and security.

3. Real-World Examples

   • Example scripts demonstrate polynomial evaluation, secure addition, and real-world applications like risk scoring in finance or medical data aggregation.
