Abstract
Published by the National Institute of Standards and Technology (NIST), Secure Hash Algorithms continue to evolve to provide increasingly stronger levels of cryptography-based security. The latest iteration, SHA-3, has a new internal computational structure as compared to previous NIST-specified hash algorithms to address known vulnerabilities of its predecessors. As embedded systems become smarter and more connected, it’s more critical than ever to safeguard them from attack. SHA-3 can help; however, implementing cryptographic hash functions can be challenging without a background in cryptography. This white paper discusses the merits of SHA-3 and highlights how secure authenticators designed with SHA-3 algorithms and physically unclonable function (PUF) technology can provide strong embedded security without requiring cryptography expertise.
