In 1999, two signature schemes based on the flexible RSA problem (a.k.a. strong RSA problem) were independently introduced: the Gennaro-Halevi-Rabin (GHR) signature scheme and the...

We construct two new multiparty digital signature schemes that allow multiple signers to sequentially produce a compact, fixed-length signature. First, we introduce a new primiti...

Sanitizable signature schemes allow a semi-trusted entity to modify some specific portions of a signed message while keeping a valid signature of the original off-line signer. In...

A transitive signature scheme allows to sign a graph in such a way that, given the signatures of edges (a, b) and (b, c), it is possible to compute the signature for the edge (or ...
