LMAO well since you have a code and the explanation can be found somewhere... what is the big deal to crack something with it???Originally Posted by toalan
BTW all alrgorithm are still human made... another can bypass it easy... really easy
no comments, some are in jail now...

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

Sorry I am not following you, my implementation is to supply people with encrypted firmware, they send it to the MCU and the MCU will decrypt the data and write it to flash memory.
If you can bypass encryption easily then you are one of the few geniuses and perhaps your work has been undocumented. As of 2004 there is been no officially successful attempts at breaking the xtea algorithim.
The xtea algorithim in xbox was never really borken, people exploited flaws in the hardware design to run unsigned code, most notably the big font flaw.

if you guys are interested in my XTEA bootloader here it is http://www.14point7.com/AVR.htm

I will need to use encryption in a wireless stream for an upcoming product. XTEA looks good, and compact. I will write in assembly, but I wondered if anyone has played with this in PBP? It looks like a fun excercise, especially with the version 2.5 longs! Any other ideas for good encryption without a lot of overhead? It needs to stand up to that .01% of attacks.
Thanks,
Ron

Go to the Swordfish Basic compiler site and download their demo program; it has XTEA with it. Surely you can convert it.

I downloaded Swordfish, but cannot find any mention of TEA, XTEA, or TEA-N. Where did you find it?

Should be in "\Sample\encryption" folder.
