Abstract

In a transitive signature scheme, a signer wants to authenticate edges in a dynamically growing and transitively closed graph. Using transitive signature schemes it is possible to authenticate an edge (,)ik, if the signer has already authenticated two edges (,)ij and (,)jk. That is, it is possible to make a signature on (,)ik using two signatures on (,)ij and (,)jk. We propose the first transitive signature schemes for undirected graphs from lattices. Our first scheme is provably secure in the random oracle model and our second scheme is provably secure in the standard model.
