Advanced digital signature functionality from group theory
Post-quantum group-based cryptography · Historical workshop question
Inferred from the community field; finer classification has not been reviewed.
Problem statement
We would like to use generic group-action tools to build ring signatures, blind signatures, threshold signatures and more. We would also like to apply the "twist" technique present in similar isogeny schemes to improve the memory performance of group-based digital signatures.

Background
Section context
Open problems relating to the design of protocols in group-theoretic cryptography.
Question context
The connection between SDLP and group actions suggests the availability of generic group-action tools to build more efficient signatures, or signatures with more specialised properties.
