Calculating differentially private average of a dataset
I was looking into Google's DP library and its implementation of bounded DP-average. The library implemented DP-average following the following algorithm presented in Li et al. (2016):
Proposition 2.22 Algorithm 2.3 satisfies ϵ-DP. [The] proof is…

How can I generate cryptographic-quality 1/f noise, aka “pink noise”?
Can anyone suggest how I'd generate cryptographic quality 1/f noise: aka 'pink noise', where the PSD follows 1/f.
I'd be happy to derive the pink noise from white noise (e.g. /dev/urandom), but I don't want to filter it in a way that would…

Reencrypting in Homomorphic Encryption
I am getting started with Homomorphic Encryption libraries. I am trying to port a codebase written in Python to Haskell. I see that there is a re-encryption operation happening in one part of the code. Something like this:
def re_encrypt(self,…

Noisy secret sharing
I am looking for a secret sharing scheme that is robust against noise, the shares are going to be noisy. We do not want to reconstruct the secret perfectly and a noisy reconstruction with a bound on noise is good enough.
Assume we are using $(n,k)$…

How can one model the behaviour of CKKS decryption noise?
I am trying to program a simulator for CKKS. It is a "simulator", in the sense that
there is actually no encryption involved, but
to a person seeing only the plaintexts (before encryption and after decryption) and with knowledge of the oblivious…
