Definition
The term, in context
AI-assisted draft · approved dataset
The NIST additional digital signatures process is a public evaluation run alongside the main post-quantum standardization effort, seeking signature schemes whose security rests on assumptions other than structured lattices. Its third round narrows the remaining candidates, drawn from code-based, multivariate, isogeny-based, and symmetric-key families, through further public cryptanalysis and performance comparison before any are selected for standardization.
