homenc / HElib

HElib is an open-source software library that implements homomorphic encryption. It supports the BGV scheme with bootstrapping and the Approximate Number CKKS scheme. HElib also includes optimizations for efficient homomorphic evaluation, focusing on effective use of ciphertext packing techniques and on the Gentry-Halevi-Smart optimizations.

somebody? anybody?

Hello,

my guess would be to simply look at /usr/local/lib and /usr/lib and see if the library is there.

Also use ldconfig command in linux. It can be used to see if and where a library is found and a good start would be to purge its cache and let it rebuild.

Open /etc/ld.so.conf and see if the directory (probably /usr/local/lib) is added. You can add it yourself and then run ldconfig in the console, or you can remove /etc/ld.so.conf and run ldconfig to rebuild it.

Hope this helps.

ok thanks

I feel the AES implementation APIs are not updated to reflect latest changes in the recent versions of library which include CKKS scheme as well. Will the AES implementation work for CKKS ciphertext as well??

I have found aes_compatible vertion:https://github.com/homenc/HElib/pull/343 .It does work. I think CKKS could not work,because it's an approximate homomorphic encrytion scheme,it will cause some small errors.
