There are several security modes available on the Stratix III device, which
are as follows:
Volatile Key
Secure Operation with volatile key programmed and required external
battery: this mode accepts both encrypted and unencrypted
configuration bitstreams. Use the unencrypted configuration bitstream
support for board-level testing only.
Non-Volatile Key
Secure Operation with one time programmable (OTP) security key
programmed: this mode accepts both encrypted and unencrypted
configuration bitstreams. Use the unencrypted configuration bitstream
support for board level testing only.
Non-Volatile Key with Tamper Protection Bit Set
Secure Operation in tamper resistant mode with OTP security key
programmed: only encrypted configuration bitstreams are allowed to
configure the device.
Step 1, Step 2, and Step 3 correspond to the procedure detailed in the
Design Security Solution”
