Post-Quantum Forward-Secure Signatures with Hardware-Support for Internet of Things

Advantages:

HASES ensures robust and scalable authentication for IoT applications, safeguarding against compromise risks.
HASES offers forward security without the need for expensive specialized hardware, making it practical for low-end IoT devices.
HASES outperforms existing alternatives, achieving significantly faster speeds and greater energy efficiency on 8-bit devices.

Summary:

This technology, known as HASES (HArdware-Supported Efficient Signature), represents a cutting-edge digital signature system tailored for the Internet of Things (IoT). Its primary objective is scalable authentication and non-repudiation, addressing the critical security needs of IoT applications. HASES focuses on post-quantum cryptography (PQC) that maintains efficiency while offering forward security, crucial for low-end IoT devices. A key advantage is its lightweight nature, transforming key-evolving signatures into robust ones without specialized hardware. HASES outperforms alternatives, achieving 271x and 34× faster speeds than forward-secure XMSS and plain Di lithium on 8-bit devices, with superior energy efficiency over forward-secure ANT and plain BLISS. Its open-source nature fosters collaborative testing and adoption, making it a significant stride towards fortifying IoT security.
