The 520 byte mode is important because it contains a CRC and other
"stuff" to determine the authenticity of the data...
If we did a mode that encrypted the extra 8 bytes using the counters
in this 8 as part of the tweak, and somehow manipulated the CRC so
that tamper anywhere in the packet will randomize the (puny 16 bit)
crc, this would be valuable? This way, the operation of the encryptor
will be validated end to end???
This would mean that the storage devices can not check the 2 CRC?
Stated another way, is it legal to have a 520 byte sector that does
conform to the extra 8 standard above the encryptor and below the
encryptor is a true 520 byte sector?
Comment?
Thanks
