Floating-point Vulnerability Protection

🚀 Feature

Floating-point Vulnerability Protection.

Motivation

Prevent exploiting vulnerabilities that could lead to privacy leakage.

There is no documentation that states the use of floating-point vulnerability protection as in https://scholar.google.com/citations?view_op=view_citation&hl=en&user=hg3A9TgAAAAJ&citation_for_view=hg3A9TgAAAAJ:dhFuZR0502QC
and
https://research.ibm.com/publications/secure-random-sampling-in-differential-privacy

Pitch

Additional code should be added to cover such vulnerability.

Alternatives

Sample from discrete distributions.

Additional context

Other libraries like IBM's diffpriblib accounts for this, and they also enable ML.

Hi @gonzalo-munillag

Thank you for your question and interest in Opacus.

If I am not mistaken, this vulnerability is fixed and documented in here which uses the fix in here.

I am going to close this task for now, but if you feel like your issue wasn't handled, feel free to comment here and reopen!
