Hi!

I imagine you are no longer working on that implementation, so, this question is not a request for code fixing, I just want to understand better the code to know if I am going to break something when changing it...

The class YASHEKey has a field called num_slots.

If I understood well, this value is also used as the maximum possible degree of the plaintexts, right?
In this case, when we are not using batching, we can only create plaintexts of degree equals to one, since num_slots is set to 1 at the line 146.

I changed that line to num_slots = params.n. So, could you please tell me if my understanding is correct and if you think it will break something ?

I am really thankful for your help!

Hi all,

I'm trying to design parameters to homomorphicly evaluate a function with a multiplication level=5, but according to the publication[1], in order to avoid ciphertext expansion, it was proposed to use block cipher+FHE scheme[NLV11].

Since a block cipher such as SIMON-32 has a minimum multiplication level 32, the FHE level has to be 32, even for my function it only needs to be 5. Is that so?

Thanks in advance if you kindly answer it.

Kind regards,
Husen

[1] A comparison of the Homomorphic Encryption Schemes FV and YASHE

Hello.

I just want to know if this implementation of the YASHE scheme is thread-safe. Because I am planing to use it on a multi-thread application...

Thank you very much!
