| description | PROBLEM TO BE SOLVED: To obtain an encryption technique for securely generating different keys in group units such as companies.SOLUTION: A dynamic encryption key generation system comprises: external data providing means which provides external data acquired by encrypting in advance ID corresponding data and a program control value including a program control element; and an encryption processing device. The encryption processing device comprises: external data decryption means which generates the ID corresponding data and the program control value by decrypting the encrypted external data; first key information generation means which generates first key information from the acquired ID corresponding data; second key information generation means which generates second key information from the acquired program control value; and encryption key generation means which generates an encryption key on the basis of the acquired first key information and second key information.
【課題】 会社等のグループ単位で異なる鍵を安全に生成できるようにする暗号化技術を得る。【解決手段】 ＩＤ対応データとプログラム制御要素を含んだプログラム制御値とを予め暗号化して得た外部データを提供した外部データ提供手段と；暗号化された外部データを復号してＩＤ対応データとプログラム制御値とを生成する外部データ復号手段と、得られたＩＤ対応データから第１鍵情報を生成する第１鍵情報生成手段と、得られたプログラム制御値から第２鍵情報を生成する第２鍵情報生成手段と、得られた第１鍵情報と第２鍵情報とから暗号化鍵を生成する暗号化鍵生成手段とを備えた暗号化処理装置と；を備えた動的暗号化鍵生成システム。【選択図】 図１ |
