DCRP1A

The DCRP1A - CryptOne IP is a 100% safe cryptographic system

CryptOne – a 100% safe cryptographic system based on more than 20 years DCD’s market experience. Starting from 1999, Digital Core Design mastered more than 70 different architectures (like e.g.  World’s Fastest 8051, I3C, deeply embedded 32-bit CPU), which have been utilized in more than 500 000 000 electronic devices around the globe.
DCD’s CryptOne core is a universal and fully scalable solution which is able to boost asymmetric cryptographic algorithms like:

• RSA (keys up 4096 bits) with CRT option
• Diffie-Hellman
• Elliptic Curve Cryptography (ECC) in GF(p)
• Miller-Rabin test

The energy efficient architecture of CryptOne IP core enables usage of very small silicon footprint with high processing speeds. It can be provided with various different interfaces, including AMBA AHB, AXI4 and APB. Very intuitive interface allows fast and straightforward system integration. The core is resistant to power and timing attacks. CryptOne system is universal and fully scalable, accelerating up to 4096 bits big number arithmetic operations such as: modular multiplication, subtraction, addition and shifts. Cryptographic instructions support provides ability to boost public key algorithms like RSA, Diffie-Hellman and ECC.
