Field-programmable gate arrays (FPGAs) are kind of like a computer manufacturer’s Lego bricks: electronic components that can be employed in a more flexible way than other computer chips. Even large data centers that are dedicated to cloud services, such as those provided by some big technology companies, often resort to FPGAs. To date, the use of such services has been considered as relatively secure. Recently, however, scientists at Karlsruhe Institute of Technology (KIT) uncovered potential gateways for cyber criminals, as they explain in a report published in the IACR journal.
