Abstract

PURPOSE:To protect software by ciphering a decipher key of software with an individual key of a user to obtain assent information and enabling only a regular user to decipher the decipher key from assent information. CONSTITUTION:In a software managing part 1, an individual key of the regular user is generated by an individual key generating part 3 and is reported, and software of a normal text is ciphered with the decipher key by a software ciphering part 5 to obtain a ciphered text, and the decipher key is ciphered with the individual key by a key ciphering part 4 to obtain assent information. Ciphered text software and the decipher key ciphered as assent information are transferred to the user. Though software presented from the software managing part 1 is copied, deciphering and execution without the decipher key are impossible because it is ciphered, and thus, software is protected.
