PQ‐Sigs
Post-quantum signatures (PQ-Sigs) ensure cryptographic security even against quantum attacks. NovaNet integrates PQ-Sigs to protect blockchain transactions, validator authentication, and smart contract execution.
Traditional cryptographic signatures (ECDSA, RSA) rely on integer factorization and elliptic curve cryptography (ECC), both of which are vulnerable to quantum computing via Shor’s Algorithm.
- PQ-Sigs use lattice-based, hash-based, and multivariate polynomial cryptography to secure blockchain transactions.
- NovaNet's PQ-Sigs implementation ensures future-proof validator authentication, governance voting, and AI-powered transaction security.
NovaNet integrates NIST-approved post-quantum digital signature schemes, including:
- CRYSTALS-DILITHIUM – High-speed lattice-based signature algorithm
- FALCON – Compact lattice-based post-quantum signatures
- SPHINCS+ – Stateless hash-based signatures for long-term security
| Signature Scheme | Type | Advantages | Use in NovaNet |
|---|---|---|---|
| CRYSTALS-DILITHIUM | Lattice-Based | Fast signature verification | Validator authentication |
| FALCON | Lattice-Based | Small signature size | Transaction signing |
| SPHINCS+ | Hash-Based | Quantum-resistant long-term security | AI-powered fraud detection |
Validators must sign blocks using PQ-Sigs, ensuring that block signatures remain quantum-resistant.
Let:
-
$$PK_V$$ be the public key of the validator. -
$$SK_V$$ ) be the private key of the validator. -
$$M$$ be the block data. -
$$\sigma$$ be the post-quantum signature.
Verification:
If TRUE, the validator is authenticated. If FALSE, the block is rejected.
NovaNet smart contracts use PQ-Sigs for secure execution. The AI-based contract engine verifies quantum-resistant digital signatures before executing critical contract functions.
