Abstract (in Japanese) (See Japanese page) 
(in English) We propose an algorithm for the gathering problem of mobile agents in Byzantine environments. The proposed algorithm can make all correct agents to meet at a single node in $O(fm)$ time ($m$ is the number of edges) under the assumption that each agent has unique ID and behaves synchronously, each node is equipped with an authenticated whiteboard, and at most $f$ Byzantine agents exist. Since the existing algorithm achieves gathering without a whiteboard in $tilde O(n^9lambda)$ time, where $n$ is the number of nodes and $lambda$ is the length of the longest ID, our algorithm shows a whiteboard can significantly reduce the time for the gathering problem in Byzantine environments.
