Title:
Fusion One-Time Non-Interactively-Aggregatable Digital Signatures From Lattices

Authors: Brandon Goodell, Aaron Feickert

Abstract:

We present Fusion, a post-quantum one-time digital signature scheme with non-interactive aggregation with security resting on the short integer solution problem over ideal lattices. Fusion is structurally similar to CRYSTALS-Dilithium, but Fusion is based upon the aggregatable one-time lattice-based scheme by Boneh and Kim. Fusion parameters conservatively target at least 128 bits of security against forgery, taking tightness gaps into account, and with tighter bounds than the BK scheme. Aggregate Fusion signatures are logarithmically sized in the number of keys, so aggregating enough signatures can be more efficient than stacking Dilithium or Falcon signatures.
