Post-Quantum Signatures

Post-Quantum Cryptography

Post-quantum signatures refer to cryptographic algorithms that are resistant to the powerful computing capabilities of quantum computers. These signatures are designed to replace traditional algorithms like ECDSA (Elliptic Curve Digital Signature Algorithm). Post-quantum signatures ensure the long-term security of transactions, smart contracts, and all network communications.

Post-Quantum Cryptographic Standards

By embracing advanced post-quantum cryptographic standards, such as multivariate and hash-based algorithms, Altica fortifies the network against computational advances. This strategic approach allows the blockchain to scale without vulnerability to quantum-powered attacks, positioning Altica at the forefront of blockchain security.

Quantum-Proof Architecture

Altica’s early adoption of post-quantum cryptography positions it as a leader in blockchain security. The transition to quantum-resistant algorithms not only enhances security today but also future-proofs the blockchain against emerging quantum threats, ensuring Altica remains a safe and reliable network for years to come.

Quantum-resistant algorithms, such as hash-based and multivariate schemes, ensure that blockchain networks remain secure even against powerful quantum computing attacks, which could break traditional cryptographic protocols.

Altica integrates quantum-resistant algorithms such as lattice-based (Dilithium, Falcon) and hash-based (SPHINCS+). These cryptographic methods secure transactions, smart contracts, and validator authentication against quantum threats while maintaining efficiency and scalability.

Altica integrates lattice-based key exchange protocols like Kyber and FrodoKEM, which provide quantum-resistant encryption for securing node communications, validator authentication, and cross-chain interoperability.

Lattice-based cryptography relies on hard mathematical problems like Learning With Errors (LWE) and Shortest Vector Problem (SVP), which remain infeasible to solve even with quantum computers. Altica uses these constructions to protect digital signatures and key exchanges from quantum attacks.
