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： The present invention comprises a program generation apparatus for generating an obfuscated program difficult to analyze from outside and a program execution apparatus for executing the program. The program generation apparatus comprises: an acquisition unit operable to acquire a 1st program including one or more instructions, the 1st program causing a process by executing the instructions in a predetermined order to obtain a result; a generation unit operable to generate a 2nd program based on the 1st program; and an output unit operable to output the 2nd program. Here, the 2nd program causes a process that is different from the process caused by the 1st program and varies according to current information determined at execution of the 2nd program in order to obtain a result identical to the result of the 1st program.
