In response to the rapid evolution of quantum computing, the National Institute of Standards and Technology (NIST) started a process to select quantum-resistant cryptography algorithms for standardization in 2016. After three rounds of analysis and public scrutinity, the first algorithms to be standardized were chosen by the NIST in 2022.

The security of two out of three of the selected signature schemes relies on the hardness of solving mathematical problems based on structured lattices. To mitigate the risks associated to future attacks, the NIST wishes to diversify the portfolio of hard mathematical problems underlying signature schemes hence have launched a new process to select additionnal digital signature schemes for standardization in 2023.

The Technology Innovation Institute (TII) along with 35+ partners from 10+ countries are involved in 6 out of 14 schemes that are currently considered and analyzed in the Round 2 of the NIST standardization of additional digital signature schemes project.

• 2025/02/05 - Deadline for updating signature schemes selected for the round 2.


• 2024/10/24 – The round 2 of the NIST standardization of additional post-quantum digital signature schemes project has started. Amongst the 40 proposals from round 1, the NIST has selected 14 candidates including LESS, Mirath (merge of MIRA and MiRitH), PERK, RYDE, SDitH and SQISign.


• 2023/07/18 – The round 1 of the NIST standardization of additional post-quantum digital signature schemes project has started. Amongst the 50 proposals submitted, the NIST has selected 40 candidates including Biscuit, LESS, MIRA, MiRitH, PERK, RYDE and SQISign.


• 2023/06/01 – Deadline of the call for additional signature schemes for the Post-Quantum Cryptography standardization process.
