Hello, I'm asking this question since a quick google search revealed software able to de-obfuscate p files to m files almost perfectly. Is there any way safer (wrt reverse engineering) than pcode to protect matlab code to be used by matlab (i.e. No stand alone executable)? In particular, the code to be protected calls and is called by functions/m files that cannot be obfuscated/protected (they are part of another library that cannot be modified).
Matlab will generate the P-file in the same location where the M-file is. If you delete the M-file, TestPcode still works. But the P-file is encrypted, you can't open it to look at the code. There are a couple important things. If you want the call to “help TestPcode” to work, you must provide a truncated M-file with.

We are currently using R2012b on production systems, Thank you, ------------EDIT-------------- Just to be clear. I'm not talking about information leaking from running code, debugging or anything requiring programming skills. I'm talking about decompilation of a p file to a human readable and (very likely) executable m file, by a simple command line statement. A search in google brought up software that seems able to do just that.
If you work with MATLAB, you may have heard about MATLAB P Code. It is the protected.m file. There is an online tool, but it need an authorization code and the author does not respond. Another problem appears, when you need to process MAT-files: You can write the MAT file in clear text, encrypt it and ship it to the users. What is enterprise software vendors. But then you cannot load the file directly. You have to decrypt the file at first and write it to the harddisk before load can import the data. But then you need a very sophisticated method to remove the.
Assuming that works (and it sure looks that way), is there a second line of defense to prevent proprietary algorithms being disassembled by a simple one-click operation, while mantaining compatibility/executability in the matlaab environment? Digital Electronics And Logic Design By J S Katre Pdf Files. How to download fallout 3 on xbox one. E.g.:Once upon a time, i recall m files could be compiled to mex, but it seems this is not the case anymore (or at least it seems requiring multiple steps and lots of headaches).
What leads you to the conclusion that pcoded files can easily be de-obfuscated? I am aware of the numerous ways that information can leak from a pcoded file and there are some defenses that have been posted in other answers and downloads on this site. I believe that it is simple to defend p-code from the only credible software I found to inspect pcoded files. I believe this software is capitalizing on an already posted weakness of pcoded files. I expect this software can be defeated by any function that checks the datatypes of inputs and errors on unexpected types. P-coding removes all comments and the help section securely. When the names of the internally used variables are obfustcated also, e.g.
Decrypt P File Matlab Code
'a', 'b', 'Omega13', understanding the code might be more expensive than paying you sufficiently for the source code. I've seen such obfuscated M-file in the FileExchange.

• — Convert some or all of your source code files to a content-obscured form called a P-code file (from its.p file extension), and distribute your application code in this format. When MATLAB P-codes a file, the file is obfuscated not encrypted.
Decrypt P Code Matlab
While the content in a.p file is difficult to understand, it should not be considered secure. It is not recommended that you P-code files to protect your intellectual property.
MATLAB does not support converting live scripts to P-code files. • — Compile your source code files using the MATLAB Compiler to produce a standalone application. Distribute the latter to end users of your application. Building a Content Obscured Format with P-Code A P-code file behaves the same as the MATLAB source from which it was produced.
