The algorithms behind PQCaaS

The algorithms that power ExeQuantum's API

Introduction

ExeQuantum leverages cutting-edge post-quantum cryptographic (PQC) algorithms to provide robust security solutions in an API format. Two key algorithms that form the backbone of ExeQuantum's cryptographic offerings are ML-KEM (Module Lattice Key Encapsulation Mechanism) and ML-DSA (Module Lattice Digital Signature Algorithm). These algorithms are designed to withstand quantum attacks and ensure long-term data security.

ML-KEM: Post-Quantum Key Encapsulation

Overview

ML-KEM is a lattice-based key encapsulation mechanism (KEM) that enables secure key exchange between parties without vulnerability to quantum computers. It is a finalist in the NIST Post-Quantum Cryptography Standardisation Process, making it a strong candidate for widespread adoption in post-quantum security applications.

Features

• Quantum-Resistant Security: Based on structured lattice problems that are infeasible for both classical and quantum computers to solve.

• Efficient Key Exchange: Provides strong security while maintaining practical performance suitable for high-speed applications.

• Scalability: Supports integration into various encryption protocols without significant computational overhead.

Use Cases

• Secure communication channels

• Quantum-safe TLS handshake mechanisms

• Encrypted cloud storage

ML-KEM in ExeQuantum's API

ExeQuantum provides ML-KEM as an API endpoint, allowing developers to integrate post-quantum secure key exchange into their applications. The API functions include:

• Key Generation: Generates public-private key pairs.

• Encapsulation: Produces a shared secret and encapsulated key.

• Decapsulation: Recovers the shared secret from the encapsulated key.

ML-DSA: Post-Quantum Digital Signatures

Overview

ML-DSA is a post-quantum digital signature algorithm based on module lattices. It provides quantum-resistant authentication mechanisms, ensuring data integrity and non-repudiation in digital transactions.

Features

• Strong Security: Resistant to quantum attacks, ensuring long-term validity of signed documents.

• Low Computational Overhead: Optimised for efficiency, making it suitable for real-world deployments.

• Versatility: Can be used in various digital authentication systems.

Use Cases

• Secure firmware updates

• Blockchain and cryptocurrency transactions

• Digital identity verification

ML-DSA in ExeQuantum's API

ExeQuantum offers ML-DSA as an API service, making it easy to integrate quantum-secure digital signatures into existing systems. The API functionalities include:

• Key Generation: Creates public-private key pairs for signing and verification.

• Signing: Generates secure digital signatures for messages.

• Verification: Validates signatures against public keys to ensure authenticity.
