摘要： A program conversion device generates a program by obfuscating an original program, and generates and encrypts conversion parameters for inverse conversion of the obfuscated program. The program conversion device distributes the obfuscated program together with the encrypted conversion parameters. To execute the obfuscated program, a device having a high security level decrypts the encrypted parameters by using a decryption key stored in advance, applies inverse conversion to the obfuscated program by using the decrypted conversion parameters, and executes the program resulting from the inverse conversion. A device having a low security level executes the obfuscated program without any inverse conversion.

摘要： It is troublesome for a distributor (server) to manage a plurality of programs of different obfuscated levels that are suitable for various devices, including ones having a high-speed CPU but with low security level (PCs) and ones having a low-speed CPU but with high security level (consumer products). A program conversion device generates a program by obfuscating an original program, and also generates and encrypts conversion parameters for inverse conversion of the obfuscated program. The program conversion device distributes the obfuscated program together with the encrypted conversion parameters. To execute the obfuscated program, a device having a high security level decrypts the encrypted parameters by using a decryption key stored in advance, applies inverse conversion to the obfuscated program by using the decrypted conversion parameters, and executes the program resulting from the inverse conversion. A device having a low security level executes the obfuscated program as it is without any inverse conversion.

摘要： An encrypted-data decrypting apparatus that provides enhanced security protection for programs and data while they are in the processes of decryption to execution after having been encrypted. When a decrypted partial program needs to be loaded into the shared memory M, the controlling unit 11 loads it into an area indicated by the memory location information. According to the memory location information, a plurality of partial programs are sequentially loaded into an area so that one partial program gets overwritten by another; therefore, none of the partial programs exists in the memory for a long time, and thus there is less possibility of having the partial programs referred to illegitimately. In addition, since every time some data is decrypted, the decryption support program authenticating unit 13 confirms authenticity of the decryption support program P, it is possible to prevent having illegitimate references in which the decryption support program is abused.

摘要： An authentication system that can show having an authentic computer program, can certify the authenticity of itself, and can verify the certification. The authentication system is composed of a terminal (requesting device) and a card (verifying device). The card stores secret information to be used by the terminal, and an update program for the terminal. The card verifies authenticity of the terminal using information obtained from the terminal. When it judges that the terminal is authentic, the card outputs the secret information to the terminal. When it judges that the terminal is not authentic, the card outputs the update program. With this structure, the terminal is forced to update the program when it attempts to use the secret information.

摘要： When a recording media 10 including secure areas is inserted in an electronic terminal 30, the electronic terminal 30 reads a predetermined program from the recording media 10. As a result of processing performed by the program, the recording media 10 judges a boot state of the electronic terminal 30 when the recording media 10 is inserted in the electronic terminal 30. As a result of the judgment, when the recording media 10 is inserted in the electronic terminal 30 immediately after the electronic terminal 30 is booted, the recording media 10 imposes a loose restriction of accessing the secure areas. As a point of time when the recording media 10 is inserted in the electronic terminal 30 is nearer to a point of time when the boot of the electronic terminal 30 has been completed, the recording media 10 imposes a severer restriction of accessing the secure areas.
摘要翻译：当包括安全区域的记录介质10插入电子终端30中时，电子终端30从记录介质10读取预定程序。作为由程序执行的处理的结果，当记录介质10插入电子终端30中时，记录介质10判断电子终端30的启动状态。作为判断的结果，当记录介质10在电子终端30启动之后立即插入电子终端30中时，记录介质10对访问安全区域施加了松散的限制。当电子终端30中插入记录介质10的时间点更靠近电子终端30的启动完成的时间点时，记录介质10对访问安全区域施加了更严格的限制。
