- This paper proposes the lattice-based Key Encapsulation Mechanism scheme 'Saber'. Saber is a candidate submission to the ongoing NIST post-quantum cryptography standardization project. Saber's security relies on the hardness of the Module Learning With Rounding problem and remains secure against quantum computers. The design goals of Saber are simplicity, efficiency, and flexibility. It halves the amount of randomness required and reduces the communication bandwidth compared to most lattice-based candidates. Saber provides flexibility by reusing one core component for multiple security levels. Saber is also one of the 26 candidates that have proceeded to the second round of the NIST project.
