Summary:PROBLEM TO BE SOLVED: To provide a method for improving encryption/decryption speed by complexly applying symmetric key encryption and asymmetric key double encryption.SOLUTION: A symmetric key encryption method having a high encryption/decryption calculation speed is applied to digital data of a user having high capacity. An asymmetric key double encryption method is applied to a symmetric key having low capacity used for the encryption method. Thereby, the method can greatly improve the speed of encryption/decryption to provide convenience to users.SELECTED DRAWING: Figure 2 【課題】対称鍵暗号化と非対称鍵二重暗号化を複合的に適用した暗／復号化速度改善方法を提供する。【解決手段】本発明は、容量の大きいユーザーのデジタルデータには暗／復号化演算速度の速い対称鍵暗号化方法を適用し、前記暗号化方法に使用された容量の小さい対称鍵に対しては非対称鍵二重暗号化方法を適用することにより、暗／復号化の速度を著しく向上させてユーザーに利便性を提供することができる方法を提供する。【選択図】図２
