Stratix III device designs are protected from copying, reverse
engineering, and tampering using configuration bitstream encryption.
Security Against Copying
The security key is securely stored in the Stratix III device and cannot be
read out through any interfaces. In addition, as configuration file
read-back is not supported in Stratix III devices, the design information
cannot be copied.
Security Against Reverse Engineering
Reverse engineering from an encrypted configuration file is very difficult
and time consuming because the Stratix III configuration file formats are
proprietary and the file contains million of bits which require specific
decryption. Reverse engineering the Stratix III device is just as difficult
because the device is manufactured on the most advanced 65-nm process
technology.
Security Against Tampering
The non-volatile keys are one-time programmable. Once the Tamper
Protection bit is set in the key programming file generated by the
Quartus
configuration files encrypted with the same key.
