A simple transitive signature scheme for directed trees
Transitive signatures allow a signer to authenticate edges in a graph in such a way that anyone, given the public key and two signatures on adjacent edges (i, j) and (j, k), can c...

Short Signatures from Weaker Assumptions
We provide constructions of (m, 1)-programmable hash functions (PHFs) for m ≥ 2. Mimicking certain programmability properties of random oracles, PHFs can, e.g., be plugged into ...

Deterministic Identity-Based Signatures for Partial Aggregation
Aggregate signatures are a useful primitive which allows to aggregate into a single and constant-length signature many signatures on different messages computed by different users...
