Implementing a Toolkit for Ring-LWE Based Cryptography in Arbitrary Cyclotomic Number Fields
Recent research in the field of lattice-based cryptography, especially on the topic of the ring-based primitive ring-LWE, provided efficient and practical ring-based cryptographic schemes, which can compete with more traditional number-theoretic ones. In the case of ring-LWE these cryptographic schemes operated mainly in power-of-two cyclotomics, which vastly restricted the variety of possible applications. Due to the toolkit for ringLWE of Lyubashevsky, Peikert and Regev, there are now cryptographic schemes that operate in arbitrary cyclotomics, with no loss in their underlying hardness guarantees, and only little loss computational efficiency. Next to some further refinements and explanations of the theory and additional implementation notes, we provide an implementation of the toolkit of Lyubashevsky, Peikert and Regev written in C++. This includes a complete framework with fast and modular algorithms that can be used to build cryptographic schemes around ring-LWE. Our framework ...
