摘要：
An execution program including encoded code portions is executed on an operating system inhibiting the rewriting of program code area. The execution program includes encoding target code and code not encoded. Immediately before executing the encoding target code, the encoding targets code is decoded and relocation processing is performed for the encoding target code. Immediately after starting the encoding target code, the encoding target code is not decoded. When the program execution has proceeded to the stage in which to execute the encoding target code, an area for decoding the encoding target code is allocated, and then the encoding target code is decoded within the area and thus relocated.
