I am trying to do an AES CBC Monte Carlo Test according to the pseudocode
described in section 6.4.2 (pages 8 & 9) of this NIST document:
http://csrc.nist.gov/groups/STM/cavp/documents/aes/AESAVS.pdf

According to my reading, the first iteration should be a simple encryption
of the key, IV, and PT. Yet, I can't get even my first iteration to match
the sample output in the PDF! I know my algorithm is working because it
is passing all the other tests in the PDF. I am clearly misunderstanding
something about the Monte Carlo CBC pseudocode.

Can someone shed any light on what I might be doing wrong, even for the
first iteration?

Thanks.

hi,
i would like to know details about virus/adware/malware scanner
software. Any pointers are greatly appreciated.

Thanks

Is anyone here working on this yet?

Hi,

I would like to contact Matthew Fischer who frequented here in
1995-1999.
He implemented the IDEA cipher for the Apple II in 6502.

If anyone knows how to contact him or has the IDEA implementation for
Apple II then I would appreciate hearing from you.

Thanks,

Hi,

This a protocol I'm trying to implement but I can't figure out what's
the
CRC algorithm used (assuming that it's indeed a CRC).

Here are some captures, I included those that I consider more helpful.

This packages are all 136 bytes long, all the .... are filled with
0x00,
each line is a diferent packet except the last one.

Some people claim that the earth has been visited by alien, extraterrestrial spaceships and that there has been contacts between the ETs and human scientists.

If that is true it might have happened that also some cryptographers had contacts with ETs.

I wonder if there is any evidence of extraterrestrial origin of any of our publicly known cryptographical or cryptoanalytical methods? Any doubts at all? How about NSA, has it had any help from ETs?

Hi,

Several software I download these days have the certification "Tested
spyware/malware free".. I'm really interested to know how these tests
are conducted.. do they analyze the source code?

Maybe we will also see "Tested bug free" in the future??

The poem encrypted with that machine ( from the webpage):

ETSFV FD1NV ZS7M2
UM8VK RCSZA P11IN FW-KX P/1RW
1MF4L F+3,0 QHWKS H+53- ZMTBI

QRVI8 YKK8Y

i contacted Frode Weierud about that machine, and he answered:

( translated from Norwegian):

It is not likely that anyone can break the encrypted haiku on your page,
if it is encrypted with your machine unless there is some kind of a
trick involved .
Without knowledge of the wheel connection that has a alphabet of 40
characters opposed to the enigmas 26, it is impossible.
If the clear text was known, it is possible to figure out how the
connections of the wheels. But the clear text and the encrypted text are
way to short for that method.

NEWBIE QUESTION: Key space exhaustion - How do I know when I'm there?

Suppose I'm trying to crack a cipher system by exhausting the key
space. How do I know when I've got the correct key value? The
obvious answer is look at the plaintext generated, and if it makes
sense, you've cracked it, if not try the next possible key value. How
exactly do you check that the resulting plaintext "makes sense"? I
guess if you expect the message to be in English, statistical analysis
on the plaintext is the way to go. I don't know how time consuming
this step is.

I think I read somewhere that key exhaustion is done
probabilistically: Possible candidates for the correct key are
eliminated from improbable ones statistically (??) Is this true? If
so how exactly? Partial statistical analysis of plain text?? I
thought one of the properties of a good cryptosystem is you can't find
out how close the proposed key is to the actual one, i.e. you have to
guess all the way, guessing part of the way won't help.
