Cryptography is one of several techniques or methodologies that are typically implemented in contemporary electronic systems to construct a secure perimeter around a device where information or digital content is being protected. This data must also be safeguarded when it is communicated outside of the device. Other types of security measures such as secure boot code and run-time security are different sorts of security techniques from cryptography. This white paper is focused on cryptography, one of several methods which are employed in security subsystems.
