Cryptography is the science that studies secure communication in the presence of third parties. To do this, it uses a lot of tools from various areas such as Pure Mathematics, Computer Science, and even Engineering. Modern-day cryptography relies heavily on hard mathematical problems that come from Number Theory or other areas of mathematics, like factoring a product of two large primes, computing discrete logarithms, finding short vectors in lattices and decoding linear codes.
Cryptography is everywhere in our daily lives, and everyone is familiar with concepts such as Encryption, Authentication and Digital Signatures. As we delve deeper and deeper in a digital era, it is fundamental to ensure that cryptography can provide us with reliable methods for protecting our information. In particular, one of the most important and time-sensitive matters is designing Post-Quantum secure primitives. In fact, most of the cryptography in use today will be vulnerable once quantum computers with enough computational power is available. The process for designing, testing, optimizing and standardizing cryptographic primitives is long and intense, and with this in mind, the National Institute of Standards and Technology (NIST) has launched a competition to select a range of post-quantum primitives to become the new public-key cryptography standard.
