Embodiment Construction
[0018] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0019] like figure 1 As shown, a cross-platform source code virtualization protection method based on an intermediate language interpreter described in the embodiment of the present invention includes the following steps:
[0020] Step 101: Convert the source code into an intermediate language to generate an original intermediate file;
[0021] Step 102: Obfuscate the original intermediate language to generate an obfuscated intermediate file;
[0022] Step 103: modify the bitcode generation rule of LLVM according to the bitcode file format table of LLVM, and convert the obfuscated intermediate file into a random format bitcode file;
[0023] Step 104: modify the original bitcode interpreter according to the converted random format bitcode file, and obtain the bitcode interpreter corresponding to the converted random format b...
