Lightweight Cryptography Standardization Process: NIST Selects Ascon
February 07, 2023

Share to Facebook Share to Twitter

The NIST Lightweight Cryptography Team has reviewed the finalists
based on their submission packages, status updates, third-party
security analysis papers, and implementation and benchmarking
results, as well as the feedback received during workshops and
through the lwc-forum. The decision was challenging since most of the
finalists exhibited performance advantages over NIST standards on
various target platforms without introducing security concerns.

The team has decided to standardize the Ascon family for lightweight
cryptography applications as it meets the needs of most use cases
where lightweight cryptography is required. Congratulations to the
Ascon team! NIST thanks all of the finalist teams and the community
members who provided feedback that contributed to the selection. 

NIST's next steps will be to:

  * Publish NIST IR 8454, which describes the details of the
    selection and the evaluation process
  * Work with the Ascon designers to draft the new lightweight
    cryptography standard for public comments
  * Host a virtual public workshop to further explain the selection
    process and to discuss various aspects of standardization (e.g.,
    additional variants, functionalities, and parameter selections)
    as well as possible extensions to the scope of the lightweight
    cryptography project. The tentative dates for the workshop are
    June 21-22, 2023. More information will be provided in the
    upcoming weeks.
