Hi all,

the latest Paperworld fare (Frankfurt, Germany, 25th-29th January) has
shown once again that the 3rd party manufactures are not yet able to
build compatible cartridges.

One of them (Pelikan) claimed that a super computer would need around 10
years to understand the encryption.

One ot the questions (named by Peach) was how Canon does justify the
need for such a strong encryption. I wonder whether there will be any
legal actions how good such a protection may be. What's more important:
protect one's own profits, or a possible right for 3rd party companies
and customers to obtain replacement parts from other sources.

"Our SUPER-HYPER encryption is iron-clad and will never ever be cracked no matter
how sophisticated out-of-this-world equipment is used!! Wow!!"

...ywo weeks later...

Newsbulletin: "A thirteen year old schoolboy cracks the so-called super-hyper
encryption while waiting for schoolbus using a hand-me-down hand-held computer
and posts the five line perl script on the internet..."

;-)

However, I do not know any claim from Canon about how good their
protection was. It's just about the 3rd party companies that seem to be
suprised how good it is.

I guess a rather simple encryption algorithm (AES? PGP?) with a
reasonable key length would be rather strong. I guess it's easier to
steal the key than to crack it.
