Xiphera Ltd.

Select

XIP3322B from Xiphera is a versatile Intellectual Property (IP) core designed for SHA-256 cryptographic hash function with extended support for HMAC message authentication code and HKDF key derivation function that are based on using SHA-256. SHA-256 is one of the most commonly used hash functions and is used in numerous cryptographic applications. XIP3322B offers a good balance between performance and resource requirements. XIP3322B has been designed for easy integration with FPGA- and ASIC-based designs in a vendor-agnostic design methodology, and the functionality of XIP3322B does not rely on any FPGA manufacturer-specific features.

Key Features

Versatility: XIP3322B supports the widely used cryptographic hash function SHA-256. It also has native support for commonly used message authentication code (HMAC) based on SHA-256 and key derivation function (HKDF) based on HMAC. This allows using XIP3322B for multiple cryptographic functions —for example, TLS 1.3 [4] —more easily and efficiently than an IP core that supports only SHA-256.
Constant Latency: The execution time of XIP3322B is independent of the message and key values (apart from message length), and consequently provides protection against timingbased side-channel attacks.
Performance: XIP3322B provides high performance and reaches hashing speeds of several hundreds of Mbps.
Compact Size: XIP3322B has compact size (for example, 1322 ALMs and, 3 M20K blocks in Intel® Cyclone® 10 GX family) permitting integration into resource constrained FPGA designs.
