Finalists

The following table lists the ten Finalists of the lightweight crypto standardization process.

Official comments on the Finalists should be submitted using the "Submit Comment" link for the appropriate algorithm.

We will periodically post and update the comments received to the appropriate algorithm.

All relevant comments will be posted in their entirety and should not include PII information in the body of the email message.

Please refrain from using OFFICIAL COMMENT to ask administrative questions, which should be sent to lightweight-crypto@nist.gov
