- 隠されるべき情報が地上から人口衛星に伝送されることを特徴とする、請求項5に記載の方法。
- 長いビット列である、隠されるべき情報(3)が暗号化されたメッセージを用いて、地上から動的に変更されることを特徴とする、請求項1〜7のいずれか一項に記載の方法。
- 隠されるべき情報が新たなシーケンスの伝送により変更されることを特徴とする、請求項8に記載の方法。
- 隠されるべき情報が、新たなシーケンスを生成するために新しいシードの伝送によって変更されることを特徴とする、請求項8に記載の方法。
- 機上に記憶されるのが隠されるべき幾つかの情報の項目であり、変更の命令が機上に記憶された情報項目の1つを選択するために伝送されることを特徴とする、請求項6に記載の方法。
- 分散された暗号(4)が、暗号化されたメッセージを用いて地上から動的に変更されることを特徴とする、請求項5〜11のいずれか一項に記載の方法。
- 長いビット列である暗号が、新たなシーケンスの伝送によって変更されることを特徴とする、請求項12に記載の方法。
- 暗号が、新たなシーケンスを生成するために新しいシードの伝送により変更されることを特徴とする、請求項12に記載の方法。
