Q-Day Is Approaching. CHANGING BuildsYour Foundation for a Post-Quantum Future.

Not Just New Algorithms, but New Security Standards.

From RSA and ECC to LMS/HSS and Lattice Crypto, CHANGING supports major NIST PQC candidates. We ensure compatibility and security at every step.

PQC in Action, Proven in Semiconductors.

We've already deployed PQC in semiconductor workflows. CHANGING turns theory into real-world cybersecurity strength.

Trusted for Readiness, Not Just Response.

We test PQC modules and migration paths today to secure tomorrow's systems—before new threats appear.

Secure Chips Enable Built-In Protection

Not Just Compatible With Chips, But Securing Every Layer From Boot to Transmission.

CHANGING works with secure chip makers to integrate PQC at the hardware level. Using SE, TrustZone, and crypto modules, we reduce load, enhance speed, and enable core functions like key encapsulation, device authentication, and secure storage.

Secure Boot With Protected Keys and Credentials

TPM（Trusted Platform Module） is widely used in laptops and servers for secure boot, disk encryption, and integrity checks. CHANGING integrates TPM to enable key storage, PQC certificate deployment, and device verification, improving risk visibility.

Power-Efficient and Isolated Security Core for IoT

Secure Elements have isolated zones for processing and protection. CHANGING stores and verifies PQC keys, certificates, and device IDs in SEs to ensure encryption integrity with low power use.

HSM Supports Scalable PQC Operations

HSM is essential for data centers and cloud apps. CHANGING's Ciot KMS works with HSM to perform PQC key generation, encapsulation, and signing, helping enterprises manage crypto migration and compliance.

What Is Post-Quantum Cryptography (PQC)?

Post-Quantum Cryptography (PQC) is designed to withstand attacks from quantum computers. Traditional encryption methods like RSA and ECC rely on problems that quantum computing will eventually be able to solve. Shor's algorithm demonstrated this possibility back in 1994.

PQC is based on mathematical problems that remain secure even in the quantum era. These include lattice-based cryptography, LWE, hash functions, and code-based schemes. NIST is leading the global effort to standardize PQC algorithms for future use.

Making PQC Work Efficiently With IoT Devices

Lightweight PQC Implementation

Optimized algorithms reduce memory and CPU load, making PQC suitable for IoT and edge environments.

Faster Performance With Accelerator Support

Hardware accelerators and incremental processing cut signing and verification time for real-time use.

Hybrid Approach for Smooth Migration

Combines PQC with legacy crypto to ensure compatibility and strong security during transition.




What Is a Hardware Accelerator?

A hardware accelerator is a built-in circuit that speeds up tasks like hashing, key generation, and decryption. CHANGING uses accelerators such as hash engines to boost PQC performance, reduce CPU load, and lower power use—ideal for IoT and edge devices.

What Is Incremental Computation?

Incremental computation breaks tasks into smaller steps based on available resources. It prevents overload, improves stability, and enables faster response in real-time scenarios like smart factories, connected cars, and remote sensors.



What Are the PQC Standards and Where Do They Stand Today?

NIST launched the PQC standardization project in 2016. In July 2022, the first algorithms were selected, and in August 2024, the first FIPS standards were published. PQC is now in the deployment phase.

  1. Encryption/Key Exchange :
    ML-KEM (FIPS 203, formerly Kyber), standardized in August 2024.
  2. Digital Signatures :
    • ML-DSA (FIPS 204, formerly Dilithium)
    • SLH-DSA (FIPS 205, formerly SPHINCS+)
    • LMS/HSS (IETF RFC 8554), used since 2019, common in IoT.
  3. Upcoming :
    HQC (code-based), selected as an alternate encryption method. NIST plans to finalize it by 2026.

As of mid-2025, the core PQC algorithms are fully standardized and ready for adoption. Developers can begin implementation based on the latest FIPS standards.
