Abstract | Provided is a key management system that includes a first system, a first server and a second server, wherein: the first system holds a first authentication key for authentication of the first system by the second server; the first server transmits, to the second server, an instruction to overwrite the first authentication key using an updated key with which the second server cannot authenticate the first system; and the first server and/or the second server monitors whether the first system obeyed the overwrite instruction, monitors authentication processing between the first system and the second server, and if authentication between the first system and the second server fails and the first system is determined to have obeyed the overwrite instruction, outputs a determination result indicating that the first authentication key was deleted from the first system.
L'invention concerne un système de gestion de clés comprenant un premier système, un premier serveur et un second serveur, dans lequel : le premier système conserve une première clé d'authentification pour l'authentification du premier système par le second serveur ; le premier serveur transmet au second serveur une instruction destinée à remplacer la première clé d'authentification par une clé mise à jour avec laquelle le second serveur ne peut pas authentifier le premier système ; et le premier serveur et/ou le second serveur effectuent une surveillance pour déterminer si le premier système obéit à l'instruction de remplacement, surveille le traitement d'authentification entre le premier système et le second serveur, et si l'authentification entre le premier système et le second serveur échoue et si le premier système a atteint l'instruction de remplacement, délivre un résultat de détermination indiquant que la première clé d'authentification a été supprimée du premier système.
第1システムと、第1サーバと、第2サーバと、を含む鍵管理システムにおいて、第1システムは、第2サーバが第1システムを認証するための第1認証鍵を保持し、第1サーバは、第2サーバが前記第1システムを認証不可能な更新鍵、を用いた第1認証鍵の上書き指示を、第2サーバに対して、送信し、第1サーバ及び第2サーバの少なくとも一方は、第1システムが上書き指示に従ったか否かを監視し、第1システムと第2サーバとの間の認証処理を監視し、第1システムと第2サーバとの間の認証が失敗し、かつ第1システムが上書き指示に従ったと判定した場合、第1システムから第1認証鍵が削除されたことを示す判定結果を出力する。 |
