Mathematically sound crypto can’t be broken – because it’s mathematically proven! And we know that cryptographers are very clever people. BUT … when the ‘mathematically secure’ algorithm is running on a device that an attacker has physical access to – things may change. The hardware and implementation may suddenly become vulnerable. Fault injection looks at ways of modifying the physical environment of a device with the aim of making it produce an error. And maybe that error can be used to retrieve secret information. When an error is produced, we don’t always know what we did – did we create a ‘useful’ error or a ‘useless’ error’? In this talk I’ll demonstrate how fault injection works and how my research makes finding a ‘useful fault’ less tedious!
