Occur error when run the frontend.exe with different size of set for each party

[StarKirby1102]

When I execute the program with different size of set for each party, such as:
P1: 2^12
P2: 2^14
P3: 2^16...
The program will throw exception. But I find that the paper KMP+2017 said that the OPPRF supports the different size of set:

So, how to solve this question? Thanks.

No idea, look at the code. But likely if the implementation section of the paper doesn't benchmarked different size sets then they didn't implement it. Not my paper

Sorry! It's my fault.

Thanks for reply!

@nitrieu Sorry to disturb you. I'm learning the code for KMPRT17, but the question of set size mentioned above I can't execute the frontend.exe successfully, so could you please have a look? Thanks!

hello! I also have this problem, do you have idea now?
I don't know where to modify the source code.

I took a look at the code and it appears to assume all parties have the same set size. Looks like this is the file to modify. https://github.com/osu-crypto/MultipartyPSI/blob/implement/frontend/OtBinMain.cpp

Does not look like a simple fix...
