CLP-23: RSA and Elliptic Curve Public Key Accelerator

Public key cryptography requires complex mathematical operations which are best accomplished through a dedicated co-processor in order to maximize performance. The CLP-23 implements the most computationally intensive part of the mathematics required for both RSA operations as well as the algorithms used in prime field Elliptic Curve Cryptography. When combined with the EllipsysTM software toolkit, the designer can accelerate the asymmetric cryptography required in public key algorithms with optimal offload of the embedded processor.

Key Features:

• Offloads the computationally intensive parts of public key cryptography
• Core acts as a processor peripheral
• AMBA/AHB slave interface
• Scalable through build time options:
• 2.6 RSA/s and 14 EC/s in 26K ASIC gates
• 58 RSA/s and 121 EC/s in 45K ASIC gates
• 594 RSA/s and 872 EC/s in 197K ASIC gates
• Ellipsys toolkit for RSA operations such as encrypt, decrypt, sign and verify
• llipsys toolkit for prime field ECC operations such as ECDSA and EC-Diffie-Hellman

Applications:

• IPsec and SSL gateways
• WiMax applications such as 802.16
• E-commerce and m-commerce acceleration
• Military communications systems
