1. Stratix II FPGAs have been validated as conforming to FIPS-197
standard. You can refer to the NIST web site:
http://csrc.nist.gov/cryptval/aes/aesval.html.

2. NDA is no longer required for using the design security feature. NDA
is still required for getting more information about the key protection
as this adds one more level of protection.

3. Readback is not available in Stratix II FPGAs, so there is no risk
of configuration file being read out after decryption.

4. Additional measures are taken to protect the encryption bits; some
will be discussed in the net seminar while other details are only
available under NDA.
