摘要： An obfuscating apparatus creates a table for inputting the same number of arguments for multiplying and squaring operations, and sets the output values of the table so that the outputs may depend on the arguments. With regard to the squaring operations, there are added and tabulated adding operations using the arguments necessary only for the multiplications, so that the number of arguments is equal to that of the multiplication operations. The outputs depend on all the arguments, so that the presence or absence of the added arguments is unknown unlike the case in which dummy arguments that are not processed are added.

摘要： Provided is an obfuscating apparatus for making a program analysis more difficult. The obfuscating apparatus creates a table for inputting the same number of arguments, for multiplying and squaring operations, and sets the output values of the table so that the outputs may depend on those arguments. To the squaring operations, more specifically, there are added and tabulated the adding operations using the arguments necessary only for the multiplications, so that the number of arguments is equalized to that of the multiplications. In this case, moreover, the outputs depend on all the arguments, so that the presence/absence of the added argument is unknown unlike the case, in which dummy arguments not to be actually processed are added.

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.
