Hardware accelerator for RSA, DSA, Diffie-Hellman, El-Gamal and Elliptic Curves algorithms

Overview

The Public Key Cryptographic Coprocessor (PK2C) is a hardware accelerator intended to speed-up the core functions of public-key cryptography algorithms such as RSA, DSA, Diffie-Hellman, El-Gamal or Elliptic Curves (ECC).

Key Features

Direct Memory Access (DMA) and arbiter
shared memory: no extra silicon cost; inputs and results directly accessible by software
multiple arithmetic operations: integer multiply, multiply & accumulate, square, addition, subtraction; modular multiplication
all 32 bits multiple operations up to 8192 bits
efficient software control through stackable operations: the next operation can be anticipated to avoid software slowdown; the next operation is stacked then automatically executed once the PK2C is available
configurable architecture: small or fast RTL implementations available; gated clock insertion ready
support CRT to speed-up RSA
gate count smaller than 10 kgates
straightforward integration through AMBA 3 AHB-Lite interface (customized on request)
PK2C-optimized software libraries available (RSA, DSA, DH, El-Gamal and ECC)
typical consumption of contactless protocol smaller than 4 mA in a 130 nm implementation
