Abstract(in English) | Steven H.Low and Nicholas F.Maxemchuk formulated in 1998 a collusion problem, which is to determine whether it is possible for a group of colluders to reveal secret data by combining their knowledge. However, their formulation of collusion has some drawbacks that each colluder must expose her own secret key and that it cannot properly express the way how collusion is formed. Therefore we propose a collusion model, in which the secret keys of colluders are not shared and a directed graph to represent the collusion condition is introduced. Furthermore, we present an algorithm that determine whether the collusion succeed or not. |
