128 bit security level

FHE Questions

If this is already posted please direct me there. I running through the examples and looking at the 128 bit integers examples. In doing so I changed a setting in one of the files (the Makefile? Install.sh) to change it to build in 128 bit mode. I wanted to change this back but I cannot find it, can someone tell me where they think this happened?

I know “To turn on the 128-bit mode, run “cmake -DNATIVE_SIZE=128 …”” is written in the advanced real numbers example and so I know I can do this to turn it on, but I know I basically did this in the install file but I cannot find it back.

I looked in the Makefile but there are a few? and I also looked in install.sh where I thought it was but I dont see it. I did it about a month ago so im lost. Thanks

You should look at the top-level CMAKE file CMakeLists.txt

if( NOT NATIVE_SIZE )
   set( NATIVE_SIZE 64 )
   # set( NATIVE_SIZE 128 )
endif()

cmake -DNATIVE_SIZE=128 and the opposite is cmake -DNATIVE_SIZE=64

I’m marking this as solved, but feel free to unmark it and follow up with any further questions
