Nonsense. DES is a 56 bit cipher. Because this is too short, DES is
only used in one of it's Triple-DES variant, which has an effectiv
key length of up to 112 bits. There is no indication that anyone is
able to break a 112 bit key.
The 1024 bit is probably an asymmetric cipher (like RSA) which you
can't compare with a symmetric cipher (like 3-DES or AES).
It is quite some time ago that I read the ICC 2000 report, but I can't
remember that they say that the NSA is able to break 1024 bit RSA.
Currently we even can't think on how to do this - unless someone comes
up with a very new factoring algorithm, but in this case you can't be
sure whether RSA would be safe at all. Even a 768 bit RSA key is
currently no breakable.
