Messing with your Radio Time Signal
Last month two Chinese researchers gave a presentation titled “Time is on my Side” during the “Hack in The Box” 2016 SecConf event in Amsterdam, NL (https://conference.hitb.org/hitbsecconf2016ams/) . In this presentation, the researchers outlined a way to attack NTP servers by spoofing AM and GPS radio signals which are used as the time reference by most […]
HOW to use redundancy for your NTP network
By Andreja Jarc. There are a number of methods to assure highly available and reliable operation of time & frequency synchronization in your networks.
