Homomorphic encryption is a groundbreaking cryptographic technique that allows computations to be performed on encrypted data without decrypting it first. This means data remains private during processing, making it ideal for secure cloud computing and privacy-preserving applications.
Key Features 🌐
- Mathematical Operations: Supports addition, multiplication, and more on encrypted values
- Use Cases:
- Secure data analysis
- Privacy-compliant machine learning
- Confidentiality in cloud storage
- Types:
- Partial Homomorphic Encryption (PHE): Single-operation support (e.g., RSA)
- Somewhat Homomorphic Encryption (SHE): Limited multi-operation support
- Fully Homomorphic Encryption (FHE): Unlimited operations (e.g., Google's FHE library)
Security & Privacy Protection 🛡️
Homomorphic encryption ensures:
- Confidentiality: Data stays encrypted during processing
- Integrity: Prevents tampering with encrypted results
- Authorization: Only authorized parties can decrypt final outputs
