<p>A transitive signature processing method in a undirected graph-shaped network including user terminals comprises a step in which a first user terminal receives a created public key and signature key with regard to the first user terminal based on a random matrix created according to a trapdoor generation algorithm and a trapdoor matrix corresponding to the same and a step in which the first user terminal creates a lattice vector extracted according to a Gaussian sampling algorithm as a signature with regard to a message transmitted from the first user terminal to a second user terminal.</p> |
