To realize authentication of operation of a work machine, although a use situation of the work machine changes.SOLUTION: A storage part (53) stores first authentication information C1 when a work machine (10) is in a first use situation. A use situation acquisition part (35) acquires (S11) a second use situation of the work machine (10). An authentication information generation part (37) generates (S30) second authentication information C2. An authentication control information determination part (55) determines (S23) a permissible value C3 of the second authentication information C2, according to comparison between the second use situation and the first use situation. A determination part (57) determines (S50) whether or not to permit authentication by comparing the second authentication information C2 to the permissible value C3.SELECTED DRAWING: Figure 4

    【課題】作業機械の使用状況が変化しても、作業機械の作動の認証を実現できるようにする。【解決手段】記憶部(53)は、作業機械(10)が第1使用状況のときの第1認証情報C1を記憶する。使用状況取得部(35)は、作業機械(10)の第2使用状況を取得する(S11)。認証情報生成部(37)は、第2認証情報C2を生成する(S30)。認証制御情報決定部(55)は、第2使用状況と第1使用状況との比較に基づいて、第2認証情報C2の許容値C3を決定する(S23)。判定部(57)は、第2認証情報C2と許容値C3とを比較することで認証を許可するか否かを判定する(S50)。【選択図】図4
