Key Features

Standard Compliance: XIP3327C is compliant with NIST FIPS 180-4 Secure Hash Standard (SHS) [2], FIPS 198-1 The Keyed-Hash Message Authentication Code (HMAC) [1], and RFC 5869 HMAC-based Extract-and-Expand Key Derivation Function (HKDF) [3]. Consequently, XIP3327C can be used in multiple cryptographic applications.
Versatility: XIP3327C supports the widely used cryptographic hash functions SHA-256 and SHA-512. It also has native support for commonly used message authentication code (HMAC) based on SHA-256 and key derivation function (HKDF) based on HMAC-SHA-256. This allows using XIP3327C for multiple cryptographic functions —for example, TLS 1.3 [4] —more easily and efficiently than an IP core that supports only SHA-256 or SHA-512.
Constant Latency: The execution time of XIP3327C is independent of the message and key values (apart from message length), and consequently provides protection against timingbased side-channel attacks.
Compact Size: XIP3327C has compact size (for example, 1199 LUTs and, 2/1 RAMB36/18 in Xilinx® Zynq-7000® family) permitting integration into resource constrained FPGA designs.
