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： 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： 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： To provide a program conversion device capable of executing a program that includes a secret operation using secret information without exposure of the secret information in a memory. In an execution program generation device, with respect to an original program that includes the secret operation, a combining function generation unit generates combining function processing for applying a bitwise self-dual function to an input value, a split secret information generation unit generates pieces of split secret information by performing an inverse operation of the self-dual function, a program conversion unit generates pieces of split secret operation processing each for performing the operation between each bit value of the operand information and a corresponding bit value of a different piece of the split secret information, and replaces the secret operation processing with the pieces of the split secret operation processing and the combining function processing.
