Abstract

プログラムデータが更新された場合でも、更新したプログラムデータを元に戻すことなく、更新前の構成でシールされたデータの復号化を可能にする。情報端末であり、ＣＰＵ１０１が実行するプログラムデータの更新を証明する更新証明書を格納する更新証明書格納部１０２と、ＣＰＵ１０１がプログラムデータを実行する際に、プログラムデータの更新証明書が示す更新後のプログラムデータのダイジェストと実行されるプログラムデータのダイジェストが、同一のものであるか否かを検証し、同一である場合に更新証明書の中の更新前のプログラムデータのダイジェストを選択する選択部１０３と、を備え、ＣＰＵ１０１は、更新後のプログラムデータを実行し、選択部１０３の要求により、更新前のプログラムデータを実行した場合のプログラムデータのダイジェストの累積値を保持するセキュリティデバイスを備える。
