Hybrid Encryption System

A Hybrid Encryption System is an encryption system that combines symmetric encryption algorithms with asymmetric encryption algorithms that can support encryption performance optimization tasks.

• AKA: Combined Encryption System, Asymmetric-Symmetric Encryption System, Two-Stage Encryption System.
• Context:
  • It can typically use Asymmetric Encryption for encryption key exchange and symmetric encryption for bulk data encryption.
  • It can typically implement RSA Encryption Algorithms or elliptic curve cryptography for public key operations.
  • It can typically employ AES Encryption Algorithms or ChaCha20 for symmetric cipher operations.
  • It can typically generate Session Keys using cryptographically secure random number generators.
  • It can typically provide Authentication Mechanisms through digital signatures.
  • ...
  • It can often optimize Encryption Performance by leveraging symmetric algorithm speed advantages.
  • It can often enhance Key Distribution Security through public key infrastructure.
  • It can often support Perfect Forward Secrecy via ephemeral key generation.
  • It can often enable Multi-Recipient Encryption through key encapsulation mechanisms.
  • ...
  • It can range from being a Simple Hybrid Encryption System to being a Complex Hybrid Encryption System, depending on its encryption protocol sophistication.
  • It can range from being a Standard Hybrid Encryption System to being a Quantum-Resistant Hybrid Encryption System, depending on its cryptographic algorithm choice.
  • ...
  • It can integrate with TLS/SSL Protocols for secure communication channels.
  • It can support AI System Data Governance Frameworks through data encryption services.
  • It can enable Encryption Key Management Systems via key lifecycle integration.
  • It can complement Zero-Trust Security Architectures with end-to-end encryption.
  • ...
• Example(s):
  • Network Protocol Hybrid Encryption Systems, such as:
    • TLS 1.3 Hybrid Encryption using ECDHE key exchange with AES-GCM encryption.
    • SSH Protocol Hybrid Encryption combining RSA authentication with AES session encryption.
    • IPSec Hybrid Encryption implementing IKE key exchange with ESP encryption.
  • Messaging Application Hybrid Encryption Systems, such as:
    • Signal Protocol Hybrid Encryption using X3DH key agreement with double ratchet algorithm.
    • WhatsApp End-to-End Encryption implementing curve25519 with AES-256.
    • PGP Hybrid Encryption combining RSA key encryption with symmetric content encryption.
  • Cloud Storage Hybrid Encryption Systems, such as:
    • AWS S3 Client-Side Encryption using RSA-2048 with AES-256-GCM.
    • Google Cloud Storage Encryption implementing envelope encryption pattern.
  • ...
• Counter-Example(s):
  • Symmetric Encryption System, which uses only single shared key for all encryption operations.
  • Asymmetric Encryption System, which uses only public-private key pairs without symmetric components.
  • Hashing System, which provides data integrity without encryption capability.
