Overview

The Helion Fast Hash core family implements the NIST approved SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512 Secure Hash Algorithms to FIPS 180-3 and the legacy MD5 hash algorithm to RFC 1321. These are high performance IP cores that are available in single or multi-mode versions and have been designed specifically for use in Xilinx FPGA. The hash algorithms take as input a message of arbitrary length, process the message as a series of 512 or 1024 bit blocks, and produce as output a compressed representation of the message data in the form of a message digest, the length of which varies with hash algorithm. Applications for the hashing cores include implementations of the standard Keyed-Hash Message Authentication Code (HMAC) described in FIPS 198-1. They are commonly used in the IPsec and TLS/SSL protocols, as well as Digital Signature applications, where a hash function is required to ensure both data integrity and origin authentication.
