That would the the downfall of the cloning idea Marty. The example I gave you was far too simple to even be considered of use; in practice, usually part of the algorithm is transmitted along with the code that very algorithm, as part of the larger algorithm built into the devices, making the difficulty of reverse engineering any working system basically impossible. It has been stated that to break modern digital codes would take a supercomputer approximately one year per bit of encryption and MISTY uses either 128 or 140 bit encryption (I cannot remember which). Just my opinion but I think your son's inheritance is very safe..... provided YOU do not mash it in any way having nothing whatsoever to do with KiPass. :-)
As far as theft goes, I do not see how being able to clone an RF fob really makes that any easier. If someone were going to steal and then clone your fob, why not just skip the cloning and use the OEM fob to steal the bike?
As to picking up the transmitted code from a fob on your person, I just do not see how that is even remotely likely, if even possible. Surely you would notice someone standing w/in 5 feet of you, holding a suitcase with a whip antenna on it before you started the bike, right? And as far as following you and picking up the code, again, if ANYTHING was w/in 5 feet of you while riding, I suspect collision would be the far bigger worry.
But the person who brought this up was polite, not arrogant or dismissive of the system or anything else so I try to respond in kind by not attacking or belittling him (her?) and instead just waiting to see what s/he comes back with once s/he has more information. Not sure just when, but this thread did take an unscheduled turn into Obnoxiousville somehow.....

As nice as it would be as a legal owner to be able to get an active FOB at a more reasonable price, I truly hope that an encryption algorithm is involved so that my bike if stolen just becomes a bunch of spare parts for sale and not a viable cheap vehicle for someone else. I know, they would have to follow me as I went through 20 kph, or be nearby with a code interceptor when I started the bike to catch the signal and then have access to the bike to steal it. Still, it would be reassuring to know that even then it couldn't be done. Now these bikes are getting cheaper, but in 25 years my son is going to have a classic on his hands and the value will be much higher than it is now, and I want him to still have an almost un-steal-able bike. (last sentence was tongue in cheek wishful thinking)
