[fprint] AES1660

[Andreas]

Dear friends of AES1660,


here you find my analysis of what is happening in the usb traffic 
between win driver and AES1660:

http://www.andreas-loos.com/AES1660.zip

The zip contains virtually anything I know so far. Vasily asked for usb 
logs with complete traffic that can be compared. For this, take for 
instance log 2 (my favorite reference), log 5 and log 8.

The good news is that many commands seem to be not encrypted like in 
AES2550 (or was it AES2850?). To be CORRECT in detail: There *are* in 
fact lots of encrypted commands, as Vasily remarks, but for them 
encryption is obviously the same in each run. So I think, these parts 
can be easily reproduced as black box.

The bad news is that we still cannot switch the thing into raw mode or 
know anything about the encryption. (Thanks for your helpful comments, 
Vasily! You are probably right, keys are probably not transferred 
unencrypted and the 583 byte thing is surely not a single long key.)

Any ideas how to proceed?

Best,
andreas
