摘要： A program obfuscator of the present invention divides a target program into a plurality of blocks and determines program instructions allocated according to an input/output relation between the blocks, in order to diffuse and allocate the program instructions for calculating a value of secret information in various places of the program. More specifically, with regard to a variable for calculating the secret information transferred to and from the blocks, a value of the variable when outputted from a block is equalized to a value of the variable when inputted to a next block. A random variable conversion instruction is added to each of the blocks so that a value of the variable when outputted from each block is in a range of a value expected as an input to the next block.

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.
