100% Secure Cryptographic System for RSA, Diffie-Hellman and ECC with AMBA AHB, AXI4 and APB

CryptOne is a fully scalable, hardware-accelerated cryptographic system built on 20+ years of DCD-SEMI’s engineering experience. Designed for next-generation SoCs, FPGAs, and secure embedded systems, it delivers 100% secure asymmetric cryptography acceleration for demanding applications.

Supported algorithms include:

• Digital Signature algorithms
• RSA (up to 4096-bit keys) with optional CRT optimization
• Modular exponentiation
• Diffie–Hellman
• Elliptic Curve Cryptography (ECC) over GF(p)
• Miller–Rabin primality test

Performance That Outruns Competitive Designs

In benchmark tests, DCD’s architecture proved significantly more efficient than competing IP cores:

• Up to 25% fewer logic cells with equal performance
• Up to 50% higher performance when optimized for speed

This means engineers can achieve top-class cryptographic throughput while maintaining a smaller silicon footprint — crucial for cost-sensitive or power-constrained designs.

Ultimate ECC Performance (NIST P-256 @ 200 MHz)

• EC point multiplication: 2.5 ms
• ECDSA sign: 2.6 ms
• ECDSA verify: 3.2 ms

This level of acceleration makes CryptOne an ideal choice for secure boot, key exchange, firmware validation, IoT security modules, automotive ECUs, industrial controllers, and defense-grade electronics.

Energy-Efficient, Secure, and Easy to Integrate

CryptOne’s architecture is engineered for both high speed and ultra-low power, enabling advanced public-key operations on minimal silicon area.

Key advantages:

• Interfaces: AMBA AHB, AXI4, APB
• Fast, intuitive integration thanks to a clean, well-documented API
• Resistance to timing attacks
• Optional DPA countermeasures for high-security designs
• Full support for big number arithmetic (up to 4096 bits): modular multiplication, addition, subtraction, and shifts

With native acceleration for RSA, Diffie-Hellman, and ECC, CryptOne gives designers a unified, future-proof cryptographic engine ready for secure hardware architectures across consumer, industrial, and mission-critical applications.
