We will soon get an update from the National Institute of Standards and Technology (NIST) about its latest efforts to select and standardize quantum-safe signature schemes. While the end of the first round of this process has not yet been announced, NIST has indicated that it will happen sometime after the Fifth NIST PQC Standardization Conference, being held April 10-12, 2024. With this in mind, we wanted to summarize the submitted signature schemes to date and share our opinions on some of the candidates.
