These post-quantum cryptography algorithms are more complex than our current algorithms, and we at Rambus believe a revolution, rather than an evolution, of these existing algorithms is needed. Since 2010, they take place in another town of the world every year. Post-quantum cryptography describes cryptographic algorithms running on conventional computers (as opposed to quantum cryptography running on a quantum computer) but relying on mathematical problems that are believed to be hard for conventional and quantum computers. The PQCrypto conference series has since 2006 been the main academic research conference series devoted to post-quantum cryptography. What is post-quantum cryptography? One of the main challenges is the size of the keys themselves. In other words, post-quantum cryptography aspires to ensure that our communications, business processes, transactions and information will be safe in the age of quantum computers. At a very high level, cryptography is the science of designing methods to … Algorithm selection is expected to be completed Work on Post Quantum Cryptography (PQC) is well under way, but implementation will come with its own set of challenges. NIST plans to draft standards for post-quantum cryptography around 2022. Many papers on post-quantum cryptography are published in other academic journals and conferences. These post-quantum cryptography algorithms are more complex than our current algorithms, and we at Rambus believe a revolution, rather than an evolution, of these existing algorithms is needed. NSA’s Cybersecurity Perspective on Post-Quantum Cryptography Algorithms Lattice-based cryptography: Lattice-based cryptography derives its security from the related problems of finding a short vector in a lattice or finding a lattice vector that is close to a target vector not in the lattice. In response to requests from our National Security Systems (NSS) partners, the NSA Cybersecurity Directorate (CSD) has been asked to share its view on the remaining algorithms in the NIST post-quantum standardization effort, which can be found below. These combined efforts are crucial to the development of NIST’s future post-quantum public-key standards. This effort complements the NIST post-quantum cryptography (PQC) standardization activities. These complex mathematical equations take traditional computers months or even years to break. The Open Quantum Safe (OQS) project is an open-source project that aims to support the development and prototyping of quantum-resistant cryptography.. OQS consists of two main lines of work: liboqs, an open source C library for quantum-resistant cryptographic algorithms, and prototype integrations into protocols and applications, including the widely used OpenSSL library.
