DESCRIPTION:In recent years\, building and launching satellites has become
  considerably cheaper\, making satellite systems more accessible to an exp
 anding user base. This accessibility has led to a diverse array of applica
 tions—such as navigation\, communications\, and earth observation—that
  depend on satellites. However\, hardware limitations and operational cons
 iderations often render cryptographic solutions impractical for these syst
 ems. Furthermore\, the availability of low-cost software-defined radios ha
 s made signal capture\, injection\, and interference attacks more attainab
 le for a wider range of potential attackers.\n\nTherefore\, mitigations mu
 st be developed for satellites that have already been launched without ade
 quate protections in place. This talk introduces some of our research into
  how satellite systems are vulnerable\, as well as ways to protect these s
 ystems.\n\nBio:\nSimon Birnbach is a Senior Research Associate and a Royal
  Academy of Engineering UK IC Postdoctoral Research Fellow in the Systems 
 Security Lab of Professor Ivan Martinovic in the Department of Computer Sc
 ience at the University of Oxford. He specialises in the security of cyber
 -physical systems\, with a focus on smart home\, aviation\, and aerospace 
 security.\n\nZoom link:\nhttps://cam-ac-uk.zoom.us/j/87594645761?pwd=qlkBb
