A network provider needs to consider a method that can disclose correct information to the system user without disclosing all the information of the network graph. A previous research realizes the proofs of graph information and the connectivity based on RSA cryptography. On the other hand, a pairing cryptography has been proposed, where the data size is smaller than the RSA. Furthermore, in the previous system, the proof data increase for the size of the graph. In this research, we construct a proof scheme for graph information and the connectivity using the pairing-based encryption. As a result, the data size becomes smaller than the RSA-based. In addition, by using the bilinear accumulator, the data size of zero-knowledge proof does not depend on the number of vertexes and edges. Then, we evaluate the scheme by implementing it on a PC and measuring its processing times and data size. |
