METHOD FOR PROTECTING PROGRAM FROM INTERNAL ANALYSIS, COMPUTER READABLE RECORDING MEDIUM AND PROGRAM DISTRIBUTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide technique for protecting a program from an internal analysis. SOLUTION: This technique consists of a step in which a code for mounting a virtual machine for performing a virtual operation code is generated, a step in which the source code of the program is converted into a virtual object code composed of the virtual operation code, a step in which the virtual object code is enciphered and a step in which a code for decoding the enciphered virtual object code is generated.
