Computer Security: Past, Present & Future
/ Lueders, Stefan (speaker) (CERN)
Abstract
This presentation shall take a look at the common pitfalls when developing software or deploying computing services to the world. Attackers are on the prowl finding the usual misconfigurations, errors or blunders in such software and hardware and try to exploit them for their evil deeds [...]

White Rabbit development on Altera platform
/ Back, Antoine (speaker) (IJCLAB)
In this presentation, we will showcase the metrological evaluation of a newly developed electronic architecture—a custom carrier board built around the Altera Arria10 FPGA—which integrates White Rabbit technology. This system is an original platform tailored for high-performance frequency and time distribution, as well as precise timing capture for phased-array detectors. [...]

LockSweep (on BabyWR) status and progress
/ Jansweijer, Peter (speaker) (Nikhef) ; Asteriou, Konstantinos (speaker) (Nikhef)
Usually the WR reference clock is the source of the WR timing signals (10MHz and PPS), however, for low phase noise it is profitable to use the output of the local oscillator.
In many White Rabbit systems the local oscillator has a different frequency than the White Rabbit reference clock which leads to a fixed number of possible phase lock positions.
Using the local oscillator directly means that it must be phase aligned with the PPS in the WR reference clock domain.
The process of aligning the phase of the external oscillator in the proper phase position is called LockSweep.
LockSweep is explained and progress is reported based on experience with BabyWR..

White Rabbit in Radio Interferometry
/ Boven, Paul (speaker) (JIVE)
We examine the suitability of White Rabbit for the distribution of a reference phase signal in radio interferometers. Receptors in an interferometric array require a stable reference phase, and the phase noise due to the clock distribution could possibly lead to a reduction in the amplitude of the cross product of the signals, an effect known as 'coherence loss', which reduces the sensitivity of the observation.
We develop a method to predict the coherence loss from the measurements of the ADEV and MDEV, including a novel expression for the coherence loss due to flicker phase modulation.
We introduce a new method to calibrate the dispersion parameter alpha, which is especially convenient on already deployed fiber. [...]
