Features and Benefits
- Versatility:
- Supports the widely used cryptographic hash function SHA-256.
- Native support for commonly used message authentication code (HMAC) based on SHA-256 and key derivation function (HKDF) based on HMAC.
- Allows using core for multiple cryptographic functions for example, TLS 1.3 more easily and efficiently than an IP core that supports only SHA-256
- Latency:
- The execution time of this IP Core is independent of the message and key values (apart from message length), and consequently provides protection against timingbased side-channel attacks.
- Standard Compliance:
- Fully compliant with NIST FIPS 180-4 Secure Hash Standard (SHS).
- Fully compliant with FIPS 198-1 The Keyed-Hash Message Authentication Code (HMAC).
- Fully compliant with RFC 5869 HMAC-based Extract-and-Expand Key Derivation Function (HKDF).
- Easy Integration :
- Pure RTL without hidden CPU or software components.
- Vendor agnostics FPGA/ASIC implementation.
- Performance:
- High performance and reaches hashing speeds of several hundreds of Mbps.
- Compact Size:
- Has compact size (for example, 2779 4LUTs and, 3/4 uSRAM/LSRAM blocks in Microchip® PolarFire® family) permitting integration into resource constrained Microchip® FPGA designs.
