摘要： A method invocation modification unit modifies method invocation described in a body program to dynamic invocation and modifies the method invocation to invocation via an execution support device. An encryption unit modifies the body program by encrypting a character string designating the dynamic invocation after modification by the method invocation modification unit. Therefore, the method invocation can be hidden and understanding of the program can be made difficult.
摘要翻译：方法调用修改单元将身体程序中描述的方法调用修改为动态调用，并通过执行支持设备将方法调用修改为调用。加密单元通过在由方法调用修改单元修改之后加密指定动态调用的字符串来修改身体程序。因此，可以隐藏方法调用，难以理解程序。

摘要： An obfuscation device includes a first instruction generating unit, for each of a first process and a second process, which generates an initialization instruction for securing a management area for managing identification information indicating an instruction block that should be executed next so as to proceed with the process. Further, a second instruction generating unit generates a selection instruction (i) to make a first selection selecting a process that should be proceeded out of the first process and the second process, (ii) to make a second selection selecting an instruction block indicated by the identification information managed in the management area as an instruction block that should be executed for proceeding with the process selected by the first selection, and (iii) to cause the execution device to execute the instruction block selected by the second selection, and stores the selection instruction in a storage unit.

摘要： It is an object of the present invention to provide an obfuscation device that can achieve both sufficient obfuscation and the appropriate instruction block to be executed. In the obfuscation device, a first instruction generating unit, for each of the first process and the second process, generates an initialization instruction for securing a management area for managing the identification information indicating an instruction block that should be executed next so as to proceed with the process, and to store the initialization instruction in said storage unit. Further, a second instruction generating unit generates a selection instruction (i) to make a first selection selecting a process that should be proceeded out of the first process and the second process, (ii) to make a second selection selecting an instruction block indicated by the identification information managed in the management area as an instruction block that should be executed for proceeding with the process selected by the first selection, and (iii) to cause the execution device to execute the instruction block selected by the second selection, and stores the selection instruction in said storage unit. Furthermore, a third instruction generating unit generates an updating instruction for updating, when the second process is selected by the first selection, and when the loop instruction included in the second process is executed, the identification information regarding the first process managed in the management area to identification information indicating an instruction block to be executed next in the first process which is subsequently selected by the first selection, and to store the updating instruction in said storage unit.
