KiviHash-HMAC-SHA512 | Secure Keyed-Hash Message Authentication Code IP Core
KiviHash-HMAC-SHA512 Overview
The HMAC SHA-512 IP core enables secure Keyed-Hash Message Authentication Code (HMAC) generation using the SHA-512 algorithm. The IP core is compliant to NIST FIPS 198-1 and NIST SP 800-224. It features automatic padding and a high-speed architecture optimized for efficient processing in embedded systems. The core is designed as a fully synchronous module and supports integration via an AMBA® AXI4-Lite interface. To simplify system integration, it is delivered with a hardware abstraction layer (HAL) and platform-independent C-based software drivers. The design can be deployed on a wide range of FPGA and ASIC platforms.
