Kyber-768: Post-Quantum Key Encapsulation
The NIST-standardized lattice-based encryption protecting SynX against quantum computers.
๐ก๏ธ NIST Standardized (FIPS 203)
Kyber was selected by NIST as the primary post-quantum key encapsulation mechanism after eight years of rigorous cryptographic analysis. It is now officially standardized as ML-KEM in FIPS 203.
Definition
Kyber is a lattice-based key encapsulation mechanism (KEM) selected by NIST as the primary post-quantum standard for key exchange. Officially designated ML-KEM (Module Lattice-Based Key Encapsulation Mechanism) in FIPS 203, Kyber enables two parties to establish a shared secret key resistant to quantum computer attacks.
Key characteristics:
- Quantum-resistant โ No known quantum algorithm breaks the underlying MLWE problem
- High performance โ Operations complete in microseconds
- Compact keys โ 1,184 byte public keys (Kyber-768)
- IND-CCA2 secure โ Maximum security against adaptive attacks
How Kyber-768 Works
Kyber's security derives from the Module Learning With Errors (MLWE) problem, a mathematical challenge believed intractable for both classical and quantum computers.
The MLWE Problem
Given a system of linear equations with small random errors added, find the secret values. This problem becomes computationally intractable as the dimensions increaseโno efficient quantum algorithm can solve it.
| Kyber Variant | Security Level | Public Key Size | Ciphertext Size |
|---|---|---|---|
| Kyber-512 | ~128-bit | 800 bytes | 768 bytes |
| Kyber-768 | ~192-bit | 1,184 bytes | 1,088 bytes |
| Kyber-1024 | ~256-bit | 1,568 bytes | 1,568 bytes |
Key Encapsulation Process
- Key Generation: Alice generates a public-private keypair using lattice operations
- Encapsulation: Bob uses Alice's public key to create a shared secret + ciphertext
- Decapsulation: Alice uses her private key to recover the shared secret
- Symmetric Encryption: Both parties now share a secret key for AES/ChaCha20
Why SynX Uses Kyber-768
SynX implements Kyber-768 as its primary key encapsulation mechanism, providing 192-bit post-quantum security for all key exchange operations:
- Address generation โ Your SX address is derived directly from your Kyber-768 public key
- Wallet-to-network communications โ Encrypted with Kyber-768 derived keys
- Transaction encryption โ Private transaction data protected
- Secure channel establishment โ P2P connections quantum-safe
- HNDL protection โ Data harvested today cannot be decrypted by future quantum computers
Performance Excellence
Kyber-768 operations complete in ~30 microseconds on standard hardware. This is faster than RSA key exchange while providing dramatically stronger security against quantum attacks.
