Overview
As an alternative to using hash functions, a symmetric block-cipher such as AES can be used
to implement a message authentication code (MAC) to provide data integrity and origin authentication.
Two of the most common AES-based authentication algorithms are AES-CMAC and AES-XCBC-MAC:
CMAC mode is recommended by NIST in SP800-38B, whilst XCBC-MAC mode is specified in RFC 3566
for use with the IPsec protocol.
Helion CMAC and XCBC-MAC Solutions
Helion offer a range of AES-based authentication solutions for CMAC and XCBC-MAC modes,
covering different throughput requirements from 10Mbps up to 5Gbps. This means we have an ideal
solution providing minimum area and maximum performance whatever your application. In common
with all Helion IP, our AES-based authentication cores have been designed with each technology
firmly in mind to produce the most resource efficient results.
