KiviHash-SHA256 

Secure Hash Algorithm IP Core

KiviHash-SHA256 Overview 

KiviHash-SHA-256 is an IP core implementing the SHA-256 cryptographic algorithm, an one-way hash function compliant to NIST’s FIPS 180-4 standard. It is optimized for high speed designs and easy integration with any FPGA and ASIC designs. Automatic byte padding is included. It features a standard AMBA® AXI4-Lite interface for straightforward hardware integration and HAL, and software driver (C-code, platform independent) for simple software integration. 

Key Features

  • NIST FIPS 180-4 compliant
  • Supports cryptographic hashing for SHA-256 mode
  • Automatic padding
  • High-speed design
  • AMBA® AXI4-Lite
  • Fully synchronous design
  • HAL and software driver (C-code, platform independent)
  • For any FPGA and ASIC

Tests and Verification

  • NIST CAVS test vectors for SHA hash functions
  • Extended verification through simulation
  • FPGA integration and implementation tests
  • Unity tests for driver and whole IP Core
