PQ Crypta announces production deployment of ML-KEM-1024 (Module-Lattice-Based Key Encapsulation Mechanism), replacing traditional RSA and Elliptic Curve key exchange with quantum-resistant lattice cryptography based on NIST FIPS 203 standard.

The implementation represents a fundamental shift in how secure communications are established, moving from mathematical problems vulnerable to quantum computing (integer factorization and discrete logarithms) to lattice-based cryptography that resists both classical and quantum attacks.

"ML-KEM-1024 isn't just an incremental improvement—it's a completely different approach to key exchange. While RSA-2048 would fall to a sufficiently powerful quantum computer in hours, ML-KEM-1024's lattice structure provides security that scales exponentially with key size, offering practical quantum resistance."

ML-KEM-1024 Technical Specifications

Parameter	Value	Comparison to RSA-2048
Public Key Size	1,568 bytes	~6x larger
Ciphertext Size	1,568 bytes	~6x larger
Shared Secret Size	32 bytes	Same
Security Level	NIST Level 5	Higher
Quantum Resistance	Yes	No

How ML-KEM-1024 Works

ML-KEM-1024 is based on the Module Learning With Errors (MLWE) problem, a mathematical challenge involving noisy linear algebra in lattices. The algorithm:

Key Generation: Creates public/private key pairs from structured lattice polynomials
Encapsulation: Sender generates random shared secret and encrypts it using recipient's public key
Decapsulation: Recipient uses private key to recover the shared secret
Symmetric Encryption: Shared secret derives AES-256-GCM keys for actual data encryption

The lattice-based approach provides several advantages over classical cryptography. First, there are no known quantum algorithms that can efficiently solve the MLWE problem—even Shor's algorithm, which breaks RSA, is ineffective against lattice problems. Second, security scales better with key size, allowing smaller keys for equivalent security levels compared to other post-quantum candidates.

"Lattice cryptography has undergone rigorous analysis by the global cryptographic community over decades. NIST's selection of ML-KEM validates this approach as both secure and practical for real-world deployment."

Implementation Benefits

Proven Security: Based on well-studied hard problems in lattice theory
Efficient Performance: Faster key generation and encapsulation than RSA
Quantum Resistance: No known quantum algorithm can break MLWE in polynomial time
Structured Lattices: Module lattices provide efficiency while maintaining security
Forward Secrecy: Ephemeral keys ensure past communications remain secure
Standards Compliance: Implements NIST FIPS 203 specification exactly

PQ Crypta's implementation includes optimizations for both performance and security. Constant-time operations prevent timing side-channel attacks, while careful memory management ensures sensitive key material is securely erased. The platform achieves production-ready performance while maintaining full cryptographic correctness.

Hybrid Deployment Strategy

Recognizing that cryptographic transitions require careful planning, PQ Crypta supports hybrid modes that combine ML-KEM-1024 with classical algorithms:

ML-KEM-1024 + X25519: Combines lattice and elliptic curve key exchange
Dual Protection: Security relies on hardness of either problem
Backwards Compatibility: Gradual migration path for existing systems
Defense in Depth: Multiple cryptographic layers enhance security

The deployment of ML-KEM-1024 positions organizations to withstand cryptographic attacks from both current supercomputers and future quantum computers. As quantum computing technology advances, PQ Crypta's implementation ensures data remains protected through mathematical foundations that resist quantum algorithms.

Performance Characteristics

ML-KEM-1024 demonstrates excellent performance characteristics suitable for production deployment:

Key Generation: Sub-millisecond on modern processors
Encapsulation: Comparable to or faster than RSA encryption
Decapsulation: Efficient lattice operations with optimized implementations
Memory Footprint: Moderate requirements suitable for embedded systems
