CLP-13: Large Math Core for RSA and D-H

Public key cryptography requires complex, mathematical operations known as modular exponentiation. The CLP-13 implements the most processor intensive part of the mathematics required. When combined with Elliptic software (provided in C source code), the designer can implement the asymmetric cryptography required in the RSA or Diffie-Hellman (D-H) algorithms with minimal embedded processor load.

Key Features:

• Offload the computationally intensive parts of public key cryptography
• Core acts as a processor peripheral
• Optimized for 1024-bit RSA calculations
• 35 1024-bit modular exponentiations per second at 200MHz in 0.13um
• Area: 40,000 ASIC gates
• Source code (C) is provided for pre-computation
• Source code (C) is provided for Chinese Remainder Theorem
• Test bench provided

Applications:

• IPsec and SSL gateways
• WiMax applications such as 802.16
• Digital signature applications
• Military communications systems
