Errors are induced into systems to reveal values stored in
those systems. Examples include recent demonstrations of methods for
inducing errors so as to reveal keys stored in smart-cards and other similar
key-transportation devices, the introduction of multiple errors into
redundant systems so as to cause the redundancy to fail, and the
introduction of errors designed to cause systems to no longer be used in
critical applications.
Complexity: The complexity of error insertion is not
known, however many researchers have recently claimed to have produced
efficient and reliable insertion techniques. Th mathematics in this area is
quite new and definitive results are still pending.
