| Abstract: | This paper addresses the distributed certificates searching problem in trust management. The member set and privilege set are defined, and the forward, backward and bidirectional distributed certificates searching algorithms based on the definitions are proposed. The complexity of the algorithms is analyzed compared with the existing algorithms, and the application of the algorithms is described with an instance. The results suggest that the algorithm has high practicability and efficiency with the preprocess functions. |
