A couple of great examples of security IP for FPGAs, are SecureRF’s quantum-resistant "Walnut Digital Signature Algorithm" and "Ironwood Key Agreement Protocol". A free design example featuring these protocols is available for the Terasic DE10-Nano board, demonstrating the speed of securely authenticating messages between a host and endpoint—a significant challenge in IoT designs. Quantum attacks should be a concern for anyone developing a system that will be in the field for 10+ years. The designer needs to consider that quantum computers could jeopardize legacy security methods such as ECC and RSA. While there are no standards yet for quantum-resistant public-key cryptography, the US National Institute of Standards and Technology has initiated a process to evaluate and standardize on one or more quantum-resistant algorithms. SecureRF’s Walnut DSA algorithm is a candidate, currently under review, which may or may not become a NIST-approved standard. The point to keep in mind is that by using an FPGA, security algorithms can be implemented today, and updated later to adapt to evolving standards or changing threats.
