SUMMARY:Beware of Downgrade Attacks during the Migration to Quantum Resista
 nce
DESCRIPTION:During the quantum-resistant migration’s transitionary phase 
 there is a need for backwards compatibility and manageability. This means t
 hat old and new cryptography may be in use at the same time\, creating a re
 al risk of downgrade attacks.\nThis talk sets out the problem of limiting d
 owngrade risk during migration\, focused on the use-case of end-to-end auth
 enticated commands from an authority to a device\, which is a critical use-
 case for managing infrastructure and devices. We pose several strategies fo
 r migration and provide practical ways to mitigate and manage the downgrade
  risk and minimise the exposure time window. In this use-case the problem i
 s compounded when commands are sent one-way and do not receive a response\,
  and when it takes time to upgrade authorities and devices. Furthermore\, w
 ith new quantum-resistant standards emerging and best-practice for selectin
 g algorithms and parameter sets likely to evolve\, this transition will lik
 ely not be the last. Planning today’s migration with cryptographic agilit
 y in mind to reduce the downgrade risk during future changes is therefore i
 mportant.\nGreater recognition of the real challenges of the downgrade risk
  and how to address it will equip vendors and IT managers with strategies t
 o reduce their exposure and manage risks during their quantum-resistant mig
 ration and future cryptographic transitions. By setting out the problem we 
 also hope to establish a foundation for further research in this area that 
 many will depend on.\n\nSpeakers: Thalia Laing
