HKDF/HMAC/SHA-384


Xiphera's HKDF/HMAC/SHA-384 is a versatile IP core designed for SHA-384 cryptographic hash function with extended support for HMAC message authentication code and HKDF key derivation function that are based on using SHA-384. SHA-384 is one of the most commonly used hash functions and is used in numerous cryptographic applications. This core offers a good balance between performance and resource requirements, and has been designed for easy integration with FPGA- and ASIC-based designs in a vendor-agnostic design methodology, and the functionality does not rely on any FPGA manufacturer-specific features. 


Features and Benefits


  • Versatility: 
    • Supports the widely used cryptographic hash function SHA-384. 
    • Has native support for commonly used message authentication code (HMAC) based on SHA-384 and key derivation function (HKDF) based on HMAC. 
    • Allows using the core for multiple cryptographic functions for example, TLS 1.3 more easily and efficiently than an IP core that supports only SHA-384.
  • 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, 5112 4LUTs and, 6/8 uSRAM/LSRAM blocks in Microchip® PolarFire® family) permitting integration into resource constrained Microchip® FPGA designs.
