A Status Update on Quantum Safe Cryptography

Abstract

There is an ongoing effort to standardize asymmetric cryptography that should not be attackable by a quantum computer. The process is now into its final rounds. From 69 initial submissions from academia and industry, a small number of standardized schemes are expected in 2022-2024. The standards coming out from this work are expected to be used to secure civilian and military networks alike in the future, superseding current asymmetric techniques. In addition to providing an introduction to the process to this community, we also report on our own experiments with these schemes, highlighting which trade-offs one could prepare for.
