The topology certification tool supports the application of graph signatures to certify and prove properties of topologies. The tool is realized as an interactive protocol framework between the roles of an issuer, a prover and a verifier. The tool assumes that the topology is provided by another entity in a standard graph format. The issuer is responsible for the certification of the encoding for the topology certification framework, as well as for issuing a topology certificate to the prover. The prover compiles a zero-knowledge proof on the topology certificate to convince the verifier of the requested properties.
