Device Serialization for ProASICPLUS Devices:This application note describes the creation of a design which incorporates a device-unique value that can be used as a serialization ID or encryption key, and inserted into the design programming file during production programming. For each device, single or multiple keys of any bit length can be implemented,and these keys are accessible to the logic inside the device. These keys can be used for encryption algorithms like AES and TDES, and for design revision and serial number identification. The ability to securely create unique device serialization can safeguard against counterfeit devices and uses. ProASICPLUS device serialization, combined with advanced security features such as FlashLock? or Permanent FlashLock, enables very security-conscious designs.
