Placement of Runtime Checks to Counteract Fault Injections

Bitflips form an increasingly serious problem for the correctness and security of software and hardware, whether they occur inadvertently as soft errors or on purpose as fault injections. Error Detection Codes add redundancy and make it possible to check for faults during runtime, making systems more resilient to bitflips. Codes require data integrity to be checked regularly. Such checks need to be used sparingly, because they cause runtime overhead.
