MobilCrypto+
Dual KCMVP-Verified Crypto Module from Firmware to OS
End-to-End cryptographic security from embedded chip level to OS environment with a single vendor.
What is MobilCrypto+?
Security in the digital age starts with cryptography. At the core of every process — locking data, verifying identity, protecting communications — lies cryptographic technology. But in embedded environments like automotive or industrial devices, standard crypto solutions don't work. Memory is limited, processing power is constrained, and external updates are difficult.
MobilCrypto+ is a cryptographic module designed for these constrained environments. It features KCMVP-certified cryptographic algorithms from Korea's National Intelligence Service, covering both chip-internal (firmware) and operating system (software) environments. It also provides Post-Quantum Cryptography (PQC) to prepare for future quantum computer threats.

Product Structure
MobilCrypto+ consists of two cryptographic modules. Using both modules together enables End-to-End cryptographic environment from chip level to application with a single vendor.
| Category | Mobil_FCrypto (Firmware Module) | Mobil_SCrypto (Software Module) |
|---|---|---|
| Module Type | Firmware Cryptographic Module | Software Cryptographic Module |
| Library Format | Static Library (34KB) | Dynamic Library (DLL/SO) |
| Supported Platforms | PIC32CX Series (IAR & MPLAB) | Windows, Linux, Android |
| Version | V1.0 | V1.0, V1.1 |
| KCMVP | Level 1 (CM-275-2030.8) | Level 1 (CM-266-2030.3) |
| Block Cipher | ARIA | ARIA, AES |
| Hash Function | SHA-256 | SHA-2, SHA-3, SHAKE (224/256/384/512 bit) |
| PQC | — | ML-KEM, ML-DSA |
| Optimal Environment | Embedded Systems (MCU/HSM/HSE) | Desktop · Server · OS-based Environments |
| Interoperability | Fully compatible with SCrypto | Fully compatible with FCrypto |
Architecture
FCrypto operates at the HSM/HSE Core layer, while SCrypto operates at the application layer above the OS. The two modules are connected through the Crypto Service Manager to form an End-to-End cryptographic environment.

Post-Quantum Cryptography PQC (NIST Standard)
NIST standard PQC algorithms are currently built into Mobil_SCrypto.
| Algorithm | Purpose | Module |
|---|---|---|
| ML-KEM | Key Encapsulation Mechanism | Mobil_SCrypto |
| ML-DSA | Digital Signature | Mobil_SCrypto |
Why PQC Now?
Attackers collect encrypted data today and decrypt it later when quantum computers become available (Harvest Now, Decrypt Later). Systems operating for 10+ years, like vehicles and infrastructure, are already within this threat window. MobilCrypto+ provides both conventional and PQC algorithms together, so you can start preparing now without additional system replacement.
