# 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 See https://github.com/memorysafety/ntpd-rs/issues (NTS milestone).
