Mitigation for CPA^D Security

[gy-cao]

Hello,

I am wondering if there has been any fixed for the attack in this paper https://eprint.iacr.org/2020/1533.pdf

It's primarily for schemes with approximate evaluation (CKKS) but later paper (https://eprint.iacr.org/2024/127.pdf) has also proposed attack on schemes with exact evaluation but imperfect correctness.

It seems that this issue has been for a while and someone had also posted about that in 2023.

So is there any update since then?

Thanks!
