Overview

The advent of quantum computing poses a significant threat to classical encryption algorithms, which are the backbone of secure communication over the internet. Quantum-resistant algorithms, such as lattice-based cryptography, hash-based signatures, and code-based cryptography, are being developed to counter this threat. For instance, the National Institute of Standards and Technology (NIST) has been running a competition since 2016 to standardize post-quantum cryptographic algorithms, with finalists including the likes of SPHINCS+ and BIKE. The transition to quantum-resistant algorithms will require significant updates to existing infrastructure, with companies like Google and Microsoft already investing in post-quantum cryptography research. As of 2022, the controversy surrounding the readiness of these algorithms for widespread adoption continues, with some arguing that they are not yet efficient enough for practical use. The influence of pioneers like Daniel J. Bernstein and Tanja Lange in the field of post-quantum cryptography has been instrumental in shaping the current landscape, with their work on the SPHINCS signature scheme being a notable example.
