The Helion ModExp core implements the Modular Exponentiation computation commonly used in Public-Key Cryptography. It is ideal for use in hardware acceleration of the RSA, Diffie-Hellman, and DSA key exchange algorithms.

Key Features

  • Simple 32-bit RAM interface
  • Supports 768, 1024, 1536 and 2048-bit operand lengths
  • Also supports short Exponent lengths at higher performance e.g. 180-bit for Diffie-Hellman
  • Available in a choice of versions allowing user to trade-off area and performance
  • Capable of up to ~40 1024-bit RSA operations per second (E=1024, M=1024)
  • Capable of up to ~220 1024-bit Diffie-Hellman operations per second (E=1024, M=180)
