How to extract symbol name and file name from ELF format library and replace them with other symbols?

Sivakumar Thulasingam

Hi,

I am using CCS6.1 and cgtool 7.4.17. We provide our technology in ELF library format to customers, but we should obfuscate symbols and file names in ELF library before give it to customer. Is there any TI's tool or generic tool that can read symbols and file names from ELF library and replace them with other(random) symbols. For example, if I have symbols like value_filt_in, value_filt_out, value_filt_avg, then these symbols should be changed to symbol_1,symbol_2 and symbol_3. Same way file names should be changed as well. If I have files names like, fir.obj, iir.obj, then it should be changed to file1.obj and file2.obj, as obj files are archived to create ELF library.

Thanks

This wiki article shows you how you can obscure symbols. Unfortunately, there is no feature or method for obscuring file names.

Thanks and regards,

I need symbols to be there, not removed. But symbols of different name instead of our IP symbols. Because when customer sees issues, they should able to tell the problem happening around the symbol xyz.

Unfortunately, our tools don't have features which support changing the symbol names. Have you considered using code obfuscation software?

Thanks and regards,
