# NTP update (December 2022)

## NTS

The work on an NTS key exchange and extension field parsing is progressing nicely. We did run into a problem with our two NTS testing servers [nts.time.nl](nts.time.nl) and [time.cloudflare.com](time.cloudflare.com) where we can only get one extra cookie per request (up to 8 should be possible). We'll need to follow up on that.

## New algorithm

First test results from our non-spec-compliant algorithm are very promising. So far, it looks like our approach is (slightly) better than Chrony.

## Planning the audit

We are working with a pentester of Radically Open Security to prepare for the audit that we are planning for March 2023.

# Planned work

In January, for milestone 3 (NTS) we plan to work on:

- merge NTS key exchange
- finish work on NTS packet parsing and en/decryption
- implement cookie management
